Re: Problem while using waitforbuttonpress function

[Giox79]

Thanks for your help.
I checked the suggested link, and I tried installing Octave in a different
PC (Windows XP, Octave 3.2.4, BUT WITHOUT ANY OCTAVE FORGE PACKAGE) and I
have the same problem, 

A=waitforbuttonpress()

doesn't react.

Then I installed Octave 3.2 on Ubuntu 9, and over there everything works
fine: as soon as I press a key in the window generated by the Przemek
Klosowski.

figure()

command, the 

A=waitforbuttonpress();

exit with the right A value. 

Any idea?

Thanks again for your help, any suggestion will be appreciated.
