If I hit Alt-Shift-F to reformat code when "Scanning projects" are running, the editor is locked for several minutes. I have seen this many times. Just now I pasted a javascript snippet into a .GSP and reformatted. It took 10 minutes before I could use the editor again. Every time when this happens I can see that scanning is active, so I guess it's related. Next time I will attach a thread dump.
Created attachment 84274 [details] Screen dump of locked editor. Even GUI repaint is locked.
