I've found at another bug comments about a similar trouble with ATI X300 Card.
"I have the suspicion that it is the "Animations" plugin that causes the freeze when one of the effects are activated (perhaps some pointer goes spoink). If this is the case, then further investigation would be to identify which animation is to blame.
So far I have deactivated the animations plugin and it seems to go ok :-)"
