Created attachment 122157 [details] thread dump Product Version: NetBeans IDE 7.2 RC1 (Build 201206272359) Java: 1.6.0_32; Java HotSpot(TM) Server VM 20.7-b02 System: Linux version 3.2.0-3-amd64 running on i386; UTF-8; en_US (nb) User directory: /home/radim/src/lmc/userdir Cache directory: /home/radim/src/lmc/userdir/var/cache I did D&D of some file in Files tab and the IDE started to consume almost 100% of one CPU and stopped to react. It was a file move of one file between directories in one project (Maven though I doubt it matters). I had to kill the IDE after minute or so.
Same with copy and paste using actions (not only D&D). More details: I was copying directory structure (dir with some subdir each of them containing some file, ~20-30 files total).
Some problem in FolderChildren, I guess. *** This bug has been marked as a duplicate of bug 215472 ***
