Standa, is it really necessary to call SU.invokeAndWait inside TaskScanningScope.isInScope?
unfortunately, window systems api mandates to be called from awt only. i already tried some hacking around but without much success. i'll try to come up with something better...
Well, I meant something like caching of the current file somewhere and updating the cache from AWT.
Standa was doing some changes in threading, which probably fixed this problem. Please reopen if it happens again with the new thread dump. Thanks.
