Created attachment 124368 [details] threads dump Today's build of IDE is extremely slow when use Ctrl+C/Cltr+V operations. But worst case is that using Ctrl+Shift+D just hangs IDE completely

clipboard content is rather stable when IDE works. But full IDE freeze is still in place after some time + sometimes hangs on startup as well.

I meet the same problem. When I copy a word in the IDE, the IDE does not response until 2 or 3 seconds. I did not confront this problem until few days ago. I try to use the latest netbeans and the latest jdk, but that does not work. Then I find someone said http://bugs.java.com/bugdatabase/view_bug.do?bug_id=5078787 is the problem. And the problem is somewhat about the COM in windows. So I try to install the netbeans to another Win7 PC, and the problem is gone. In that case, I guess the problem is not the netbeans, but some other application in windows. Later I uninstall some of the application I just installed few days ago. And the IDE works right now. The applications I uninstalled is "imc studio" "imc license manager" and "blueStacks" an android simulator. I guess these application may have influence to the COM of Win7. Hope my solution will help to this bug.
Seems to be a problem on Windows 10. NetBeans IDE 8.1.
Please do not reopen this issue since there was a fix made in NB 7.3 that apparently resolved the original problem. Instead please file a new issue and provide steps to reproduce and also a thread dump if the IDE hangs. Thanks.
