I'm noticing a lot of "EDT is not responding" messages under recent builds of Diana. Under Ubuntu IDEA just won't start up (I see a window on the task bar called 'Message' appear but no window/message is shown on screen). Under OSX IDEA starts up but I often see exceptions logs endlessly. The EDT messages were shown in the Maven Output window when building a project using maven. Attached is a copy of one of the thread dumps produced by IDEA from OSX.
