Kybd/mouse input intermittently not working

[rjay]

I connect to 3 PC's with Teamviewer, all Windows 7 64bit running the same version of Teamviewer.

Just one of them has an intermittent problem where sometimes the kybd input and mouse clicks just stops working and it seems like nothing I can do to get it working again other than a reboot. When it doesn't work, I can't click on anything, but the mouse pointer behaves weirdly, changing it's icon to windows resizing or text input when there is no window to resize or dialog box to enter text in.

It's been like this for many months and I keep on upgrading - and now trying the beta - but if anything it's getting worse. I completely uninstalled on the problem PC today, deleting all user data, but still the problem is exactly the same.

What keyboard and mouse is used on the target machine?
Is that a difference between it and the other systems?

It's USB mouse & kybd on all remote systems, trackpad/laptop on local system.
