Now I have to duplicate and then save. Then remove or otherwise NB freezes.
could you provide more details? I'm interested in exact steps how to reproduce and in thread dump of the freeze. You can use the StackTrace Tool to take thread dump - http://qa.netbeans.org/bugzilla/generating-thread-dumps.html Is it bug report or enhancement? thank you.
