I do not think the hardware could possibly interact that way, which leaves the software.

Try unloading all the LCD software apps and seeing ig that makes it work. Then reload until it breaks. That program is then probably causing the problem.

Its got to do with the new hotkeys CrystalControl is supporting.
A couple of other people have reported the same problem :(

The best idea might be to try an older version of CrystalControl, until i get this problem fixed.
