I recently started using Jupyter notebooks, and sometimes when I double click on a cell the text will disappear.
Sometimes by double clicking the cell directly above I can get the cell to reappear, sometimes I cannot. I haven't been able to deduce the actual commands and what's going on. Does anyone know what I'm dealing with?

I'm running a Tmux session inside a MobaXTerm SSH connection. Now if I want to select some text to be copied to the system clipboard (by holding shift pressed while dragging the mouse over the text) the selection does not work as expected.
Assume I select one word. I press and hold shift, press and hold the mouse button over the first character of the word, move the mouse to the end of the word and release the mouse button. The word gets highlighted and copied to the clipboard. This works fine.
However, now I change my mind, or discover that I selected the wrong word, and want to select a different word. Again I do the same sequence as before, but on the other word. Strangely, when I press and hold the mouse on the new word, the highlighting is not reset, but continued from the initial highlighting of the previous selection.
This is extremely annoying. I can only reset the selection by temporarily switching to a different window. It seems this problem only occurs with MobaXTerm. If I use Putty instead, the selection works fine. I checked all settings of MobaXterm, but can't find anything related to mouse events.
To clear a selected region (after selecting with shift + drag) you can either:
Right click anywhere, then left click anywhere
Shift + right click anywhere, then left click (without shift) anywhere
I think (1) sometimes does not work when I have vim in my tmux pane, but (2) works regardless.
After clearing the selection, you should be able to start another from a new location.
I can ctrl+2 to jump to my console and then type View(mtcars) to get a spreadsheet in my source pane.
I then ctrl+1 to get back to my source pane. ctrl+PgDn then moves around the tabs in my source pane. But how do I jump down to the data in the spreadsheet. I can click with my mouse in the spreadsheet and then browse around with my keyboard arrows. But I don't like using the mouse.
I'm hoping there's a keyboard trick I can do to jump from the source pane tab, down to the spreadsheet data, without having to take my hands off the keyboard to do this manually via mouse. I do it so often. And conversely, once I'm in the spreadsheet data, how do I jump back up to the source pane tabs without having to use the mouse?
Unfortunately, I don't think this is currently possible -- I've filed a feature request on your behalf on the RStudio issue tracker.
When I select a code in a Jupyter notebook cell, the code stays selected as long as I don't click into a different part of the same cell that is not selected. So, for example, if I select more text than I wanted, I have to click outside of the selection first, before being able to re-select the portion you want. This is very annoying, particularly if I select all the text within a cell and then want to select a smaller portion of text. I need to scroll up or down to the edge of the selection and click exactly before or after the selected text to unselect it again. Is there a way to make the jupyter notebook behave in a way that every click and drag creates a new selection rather than moving already selected text?
If I understood correctly, you want a way to reduce the size of the selected text area. You can do this holding shift-clicking within the selected text box, this will move the end-marker to the point where you clicked.
Unfortunately this only works with the end-marker and not the start-marker as is standard. I have raised a ticket with codemirror (the project that jupyter-notebook uses for the text editor).
I have reached an impass which means I have to spend many hours doing something in a very tedious way because I can't work out a way to do it quickly, here is my problem.
In flash if I make a button that consists of a rectangle and a text field then make it all a button symbol, if I then copy the symbol to multiple instances on screen and change the text in one of them, it changes in all of them because I am changing the symbol.
How can I overcome this, perhaps with actionscript? I tried writing.
button1.text1.text = "test change button text"; on the main canvas (and giving one button a name of button one and the text field within it text1) but it doesn't work.
The only thing I found that works was to make multiple symbol copies of the button but then if I want to change the colour or dimensions of all the buttons it takes ages.
Is there a better way? Using actionscript 2 perhaps, or just some property of the button to allow individual text?
I attempted your situation... and I didn't run into your problem. Text boxes are individual values, provided that the text box is dynamic or input
I think that what may solve your problem is checking what kind of text boxes you are working with. Look in the properties panel; does it say "dynamic"?
I am creating a mobile app using FB4.6/AIR. I am running into several issues when I have TextInput fields in my view. If I have a TextField (StageText) that has text pre-populated in it (i.e. from a data object), when the view loads, the TextField will flash the text until it eventually stops and the text disappears. Upon selecting the TextField, the text will reappear. Obviously, this is not an ideal situation. So, after doing some research, I bypassed using the StageText by using the SkinClass - 'spark.skins.mobile.TextInputSkin'. This fixed the flashing text issue, however, now upon entering text in the TextField, after a certain point, the text seems to duplicate itself several times over, so that the the word, in this case an email address, becomes unrecognizable (i.e. John.Doe#MyEmail.com would become John.Doe#MyEmail.com#MyEmail.comJohn.Doe#My).
Obviously, I need to find a solution for one of these situations. Suggestions?
Thanks, in advance.
