Alejandro,
[Please CC as I am not on the cygwin ML, thank you]
I am not sure I understand your explanation about python seg faulting.
I did read the file:
/usr/share/doc/usr/share/doc/Cygwin/python-2.3.3.README on why you
But this is still not clear to me, why a wheel event is so complicated
compare to a Button-1, Button-2 ...
BTW I don't understand why there is a difference in:
1. Starting wish, and then typing code
% proc foo { args } { puts "foo" }
% bind . "<MouseWheel>" foo
2. Writing a file contaning the same Tcl/tk code and starting is as:
$wish wheel.tcl
The solution n°1 works on my system, the solution n°2 doesn't. When
'wish' is started without argument does it loads some package I am not
aware of ?
Your help is *greatly* appreciate,
Mathieu
