Because I am lazy/overbook I think there are still some patch in the
wxVTK CVS that are not in any release unfortunately.
That's weird, I thought that the timer thingy bug only appear after
VTK 5.0. But I did it from the top of my head.

Simply that VTK mimic typical behavior of such device. If you have
ever played games, you have two typical behavior either pointing the
joystick down will make you move down, and stop as soon as you
release. Or like in a plane you have to point down, and then point up
to stop the movement
(This is pretty badly explain, but I did my best, sorry. Hopefully you
did get the big picture).

Not that I know of. Anyone on the ML to comment on that ? I think most
people using wxVTK are from academic background.
Furthermore Kitware is now officially supporting Qt and KWWidget so
for a comapny I think it make more sense to use those toolkits (IMHO).

Please send patch ;)
As far as I remember the bug was non-trivial, or require patching wx
itself. I was hoping that wx 2.8.1 would include a fix (this already
happen in the past on the 2.4.x branch)/ wx people are not extremely
serious people, when dealing with backward compatiblity.

Noone complains, because wxVTK is bug free :-P
