Hi,
first thanks a lot for your help.
I'm using a Windows XP system.
No, as soon as the windows generated by the figure command pops up, I don't
change the focus and simply try to click or type character.
I'm quite happy that in Fedora works fine, may be is simple a Windows
version issue (or that I misunderstood your question about changing focus).
The same problem happens if I write:
figure(); A=waitforbuttonpress();
on the Octave interface.
If I press a keyboard key (or a mouse button) nothing happens and the Octave
locks waiting for a button press.
If I press CTRL-C to unlock Octave, looking at A value I get:
error: `A' undefined near line 1 column 1
What happens on Fedora?
Thanks again,
Giovanni
