    Are you using Remote Desktop to connect to another machine? The rdpclip.exe process is notorious for causing problems with the clipboard. – Marek Grzenkowicz Aug 6 '09 at 8:31
  • same problem, even if I copy paste from menu, so it's not just the Ctrl-C/V shortcut. – Tomas Jul 19 '16 at 13:39

What I found:

This has to do with some application that's having a lock over the Windows Clipboard. David Candy's application should determine the Process that's causing the problem.

Download GetOpenClipboardWindow.zip from here: > http://windowsxp.mvps.org/temp/GetOpenClipboardWindow.zip

Unzip and run the tool. Post back what it reports. For best results, run this utility during the time you encounter the Copy<=>Paste problem.

So it might be some program is locking your Clipboard. Try to find out what's causing the problem and let us know.

  • I know for sure that remote desktop does that quite often – vava Aug 6 '09 at 5:07
  • that fixed the problem for me! I was using TeamViewer as a client to connect to different machine. But not even closing the TeamViewer (which was already logged off when that problem started) solved the problem. Running this program did!! – Tomas Jul 19 '16 at 13:42

I've had programs cause my Ctrl key to be "stuck" such as if I am using Synergy and move my mouse off the screen while the Ctrl key is down.

It is also possible you have Sticky keys enabled that is causing something similar(if so, hit the right side Ctrl key will "release the ctrl key again, and then go into your Accessibility settings in windows and disable sticky keys)
