IntelliJ 10.5 on Ubuntu - Caret is broken (it keeps scrolling down as I scroll my screen downwards)

Hey guys,

I i haver a long file inside intelliJ (java, properties, ruby)  if I leave my caret on Line 1 and scroll down to line 300, then the caret keeps on scrolling down with my screen as i keep scrolling down.  Is this a bug or a setting of IntelliJ?


Thanks.
