Horizontal scrollbars behaving oddly
This is not a complete show-stopping bug but Logic Express (9) recently started having issues with horizontal scrollbars -- they center themselves. Occasionally they work as they are supposed to, but most of the time they immediately return to the center, which is really irritating after a while. I'll be scrolled all the way to the end of the timeline for example, and I decide I want to scroll back left slightly; I click on the scrollbar and any kind of drag makes it jump back to the center. It acts like the mouse cursor was there, too.
Reinstallation and trashing preferences did not fix the problem.
