I'm thinking that there is *something* up with mouse moves generally. 
Simple things like hovering the mouse over a link in firefox is also a 
bit odd. Hard to describe really but it seems that the "hover" event (in 
web/js event terminology) only happens when the mouse is actually 
*moving* not when it's just settled over the link.

Of course this could be unrelated :)
