SYMPTOMS
After you install a three-button mouse and its driver and restart Windows NT, you may not be able to use all three buttons of the mouse.



CAUSE
By default, Windows NT configures all mice as a two-button mouse in the registry.



RESOLUTION
To correct this problem, you must modify the Windows NT Registry.

WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.

  Start Registry Editor and go to the following subkey:

     HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services \ \Parameters  Highlight the following entry: NumberOfButtons From the Edit menu, select DWORD. Change the Data value to 3. Choose OK. Exit Registry Editor. Shut down and restart Windows NT.</li></ol>
