EEPROM Simulation V6.

[medelec35]

After selecting and highlighting EEPROM address, manually typing a number does not allow EEPROM contents to be changed.
The only way I can edit EEPROM manually is by deleting V6 registry from HKEY_CURRENT_USER\Software\matrixmm
Now I can modify contents as normal.
I have posted a reg file which is from a PC with the issue.
Is is possible to find out what is causing the issue please?
Then I can just delete a registry key rather than the whole directory.

Thanks.

Martin.
