While editing a java source file (belongs to a project) after using CTRL+SHIFT+I (Quick Documentation Lookup) performing undo (keyboard action and menu item) produce a dialog prompting to undo quick documentation lookup. Clicking either ok or cancel dismisses the dialog but undo doesn't happen. Performing undo again causes the same dialog to appear. The undo stack is "stuck" in that editor and can't get beyond quick doc lookup. Of course other editor windows allow undo normally. Does it make sense to put quick doc lookup on the undo stack in the first place?
