I've seen this happen to me time and again on IDEA-8 as well as IDEA-9 (all the EAP versions I've tried so far). When I have a project open in IDEA and try to open another project in another IDEA window, then one of the windows becomes unusable after a few minutes i.e. you can't edit any files in that IDEA window and the only thing to do is to shut down that window and reopen it.
I remember reading about this in one of the IDEA release notes by JetBrains and am wondering whether JetBrains considers this issue important enough to fix? In my opinion, as a hardcore Linux (and IDEA) user, it becomes annoying after a while - closing down IDEA windows and reopening them. Is this a Swing issue associated with Linux workstations.
