My wife turned on her laptop 2 days ago and had the following message appear on her desktop as she brought her system up:

RTHDCPL.EXE ILLEGAL SYSTEM DLL RELOCATION

The system DLL user 32.dll was relocated in memory. The application will not function properly. The relocation occurred because the DLL C:\\WINDOWS\system32\HHCTRL.OCX occupied an address range reserved for Windows system DLLs. The vendor supplying the DLL should be contacted for a new DLL.

Can anyone explain what's up and what exactly we should do about it?

Thanks!
