Electronic Calculator - DLL/OCX Problem
Some users may be experiencing problems running Electronic Calculator due to a Microsoft Patch compatibility issue.

If you receive an error, similar to this:

The system DLL user32.dll was relocated in memory. The application will not run properly. The relocation occurred because the 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.

The problem you are experiencing relates to the Microsoft DLL USER32.DLL and also the HHCTRL.OCX file, which are core components of the Windows operating system, not specifically for Electronic Calculator.

Microsoft released an update which has caused this problem in Windows XP.  Please refer to the Microsoft article at the following address:

Follow the instructions and it should resolve your problem.
