I'm having the same problem on Win7. Plot window freezes, and closes only with "close" command. "pkg rebuild -noauto oct2mat" does not work.

I have applied the "pkg rebuild -noauto oct2mat" and am having plot windows freeze only if I click on the plot window's title bar (to move window) or try to close the plot with the close box (I can close with close command). The problem is fixed when I add "pause(25);" to the end of _plt_.m as described in http://octave.1599824.n4.nabble.com/plot-window-hangs-td1681494.html. I have tried reducing the pause time to 5 seconds, but it dosn't work (anything 25 seconds and above works, but makes plotting extremely slow). Please help!

P.S. I am using Octave 3.2.4 (mingw) on windows xp sp3

I had the same problem with Octave 3.2.4 in Windows Vista. Calling "pkg rebuild -noauto oct2mat" in command prompt fixed the problem. Plots are working fine now.

Did removing oct2mat solve the problem for you? Can this bug be closed now?

Not sure that this is related, but I had a similar problem under XP.

This section from the wiki (http://wiki.octave.org/wiki.pl?OctaveForWindows) helped to resolve it for me:


It is reported that the oct2mat octave-forge package affects plot related commands. The purpose of the package is to convert m-file into matlab-compatible coding style. Please see the documentation of the octave-forge (oct2mat - freetb4matlab) from http://octave.sourceforge.net/functions_by_package.php)
Report for this problem
Explanation of the problem
Realistic solution at this moment, do not install the oct2mat package when you install octave with octave-forge packages if you do not use this package. One one of different solutions is to execute
pkg rebuild -noauto oct2mat
at the octave prompt and then restart octave. The operation results in the oct2mat package not to be auto-loaded in startup. When you want to use oct2mat, execute "pkg load oct2mat" command.

Actually, I forgot to mention that the plot fails to even happen the first time, so that I have to repeat the command, and sometimes I get a warning - something about how isstr is obsolete and should be replaced by ischar.

The command sequence

x = linspace(0,100,1000);

results in a figure window that cannot be resized, zoomed into, etc. Any such action causes the window to freeze, although I was able to terminate it using the "close" command, so that the session is recoverable (no crash). This happened repeatedly on my Windows7 PC.
