[TxMt] Window moves when adjusting split view divider

[Jacob Carlborg]

If I click on a TextMate window to select it and the tries to adjust a 
split view divider (file browser or output view) the window moves 
instead of adjusting the divider. I doesn't always happen but sometimes 
it does.

I'm using TextMate beta5 on OS X 10.9.5. I made a screen recoding of the 
behavior:
