unzoom problem

[Paolo Buratti]

Good morning,
I have a problem with unzooming plots with octave 3.2.4 on windows xp 
(installer: Octave-3.2.4_i686-pc-mingw32_gcc-4.4.0_setup).
I can zoom by two right clicks that define a rectangle, followed by 
one left click, but, after that, if I try to unzoom by typing 'a', the 
figure becomes "not responding" and I have to throw it away.
If I make a figure directly by WGnuplot (the version which was 
installed by the same octave installer), the unzoom by 'a' works well.
In addition to having unzoom ok, the figure layout produced by 
WGnuplot differs from the one by octave: there is an extra bar with 
command icons.
I have found a similar question on mouse zoom/unzoom in the octave 
mail archive (18.08.2010), but I could not find any answer with a 
suggeted fix (the answer on 23/08 only asks what is the operating 
system).
Thank you in advance
Paolo Buratti
