Hi,
Not sure whether this is a pygtk or a gtk issue, but...
I've written an app which relies on key-press and key-release events.
Under windows XP, python 2.6, pygtk 2.16 and gtk+ 2.18 there are no
problems, however under ubuntu 9.10 (32 & 64bit) I'm seeing a
key-release event following each key-press event whilst a key is held down.
I've attached a small test case to demonstrate.
I've been scratching my head over this one for a while & can't figure it
out...
TIA,
Andy
