Selection sticks to the sceen if selected by mouse

[dnim]

Hi there!

I don't know whether it mine system configuration problem or some bugs in the 3D clipboard, but here is the issue:

1. I'm invoking list with copy/paste history
2. picking by mouse some result
3. and this result sticks to the screen (see attachment)

NOTE: if I use hotkeys - everything is fine.

OS - Windows 7 prof (SP1), Video - NVIDIA (the latest drivers are installed)

Please, ask if you need some more info.

Thank you.

Sergey
