This seems to be a problem with the tasking/GtkAda combination on Win98. I
think this example works fine on NT.
If the other example using timers works on Win98 (anim2), I would recommend
you to use that kind of feature to do the animation instead of Ada tasks.

Using tasking with GtkAda is known to work on Unix systems and I believe on NT
(from the tests we or some of our customers did), but we haven't tried it on
win98 for lack of machines.
