Erm....
I'm using XP.
I wonder what could be different. Mind if I send you a demo project?

Actually, you'll get a better S-curve with the function y=1/(1+exp(-x)).
But neither of these approaches deals with the case where the target
may move in the middle of the animation. I've had to deal with this a
few times, and finally ended up using a simple model of acceleration
and braking.
I have this partially written up and demoed for a book I'm
(occasionally) working on -- it's a bit much to post here, but if
anyone wants to see the write-up and demo, ask me off-list.
Best,

Mighty peculiar. I have a lot of games that would be broken if this
were true, but I haven't tried most of them on Linux, so it's probably
a bug peculiar to Linux or maybe even Ubuntu in particular. I
recommend filing a bug report.
