My system is kept fully up to date and I still see this problem intermittently, although not as often as I used to; I would say that this has not been fully fixed. If there are any workarounds other than rebooting, this would be a good place to collect them. This has previously been closed and re-opened due to demand.
Cutting and copying do not always seem to change the content of the clipboard, whether triggered from a keyboard shortcut, a menu option, or even drag and drop. At the least this results in sometimes praying the wrong information, at worst it results in cut randomly acting like a delete key. The behavior as I have observed started out as staying to randomly occur and then consistently happen until the system is rebooted, for all programs including finder and the terminal.now it seems to stay randomly and then intermittently but at a high frequency occur, again regardless of program.
Searching on google produces no useful results for this issue.

Can anyone explain this clipboard behaviour?
This is weird. I'm on OSX Lion, and sometimes both drag & drop and cut & paste stop working, at the same time. They stop working in any program, not just the Finder. And it's not just the shortcut: if I try to right click and select "Copy" it doesn't work either.
This has happened three times so far. A reboot fixes it, but it's annoying at best. Any solution?
