Ah, I see what the cause of my issue was. By default the tabbedpane stops at the buttons... so a tab that before was normally *just* partially obscured by the buttons was triggering the move action.

I didn't realize that before, but now that I've set the tabbedpane to be almost the full width, I'm a happy camper once again =)

Personally I wouldn't want it to autoscroll anyway, but since I don't use the scroll functionality (I always have all tabs visible) it doesn't bother me since you've fixed it not to happen when the scroll buttons aren't displayed.
