Awesome. Marking as fixed and closing report.

Yes, it works now. I haven't been able to get it to freeze. I don't even see the substitute x's when copying large data and not scrolling to load the data first.

@Marshall: Could you re-check whether this is still a problem? There has been a lot of work on the Variable Editor in January.

I'm using Linux, and things work for me pasting in to LibreOffffice.

I did

BTW, initially pasting into the variable editor did work (on Linux), but IIRC arrays got transposed in the variable editor. That observation however is from some years ago.
A WAG is that some interference from shortcuts defined elsewhere in the GUI might be related to pasting not working anymore.

Changing the "Set focus to terminal..." option didn't change anything.

Maybe it has something to do with the quantity of data copied. When I tried with smaller arrays, there was no problem. But when I did it with the larger data I first tried it with (399490 elements) then it froze the command prompt again. I tried pasting into a text editor and it did the same (working to paste, but stopping to respond only when a large number of elements was copied).

Pasting anything to the variable editor doesn't seem to work at all either from direct text, or excel, or data copied from another "cell" in the variable editor.

Works fine for me, copying into LibreOffice Calc that is.
I'm surprised copy/paste from Octave works at all, it didn't work for a long time.

Does setting "Set focus to terminal when running a command from within another widget" in the terminal preferences make a difference?

Copying from outside to the variable editor still doesn't work here; when trying to copy a 9x3 block of cells in LibreOffice Calc into a 10x3 array in the variable editor (i.e. big enough) I get:

for every row I try to paste.

I think the "x"es you mention indeed relate to the fact that the variable editor didn't yet render the values in cells outside the variable editor pane. Scrolling down and up may help.

(my box: Win 7 64-bit)

Octave stops responding after I copy data from the variable editor and paste it into excel.

I open a variable in the variable editor, then click on the top of the column (the variable I copy happens to be a single column vector), I right click and select copy column. I paste it into excel. (Sometimes some of the data is the x's that seem to suggest the data hasn't been read/shown in the variable editor yet). I return to the octave console and try to type something and nothing appears. The editor stays responsive, the variable editor appears responsive, the workspace browser seems unresponsive. I try pressing Ctl-c in the octave console to get back focus, and one of the times it briefly showed some prior text I typed earlier, but remains unresponsive after. Pressing Ctl-c more times crashes octave.
