When working on 2.0.2RC and 2.0.2 I see a text-selection / text-entry bug.
- open ruby mine with 2 editor windows side by side
- put your cursor in the left editing pane
- move to another windows (like an xterm) on your system
- return to ruby mine, highlighting text in the right editing pane
- when you start typing, your text inputs to to the left pane
- you have to double-click again in the right pane to cause the input focus to be correct
