A "unique" (?) problem with non-functioning right-click

I have what seems to be a unique right-click problem. After searching a bit, I found nothing that seemed to relate exactly to my issue.

My system is as listed in "My System Specs" (OS, CPU, motherboard, etc.).

On my system, there are setup a limited user account set, my own account (administrator-level), and also the built-in administrator account (unhidden and renamed).

MY ISSUE:

Right-click is non-functional. No context menus appear anywhere at any time.


ADDITIONAL INFORMATION:

The application key on my Microsoft Natural Elite keyboard *does* bring up context menus (discovered this by chance).

Right-clicking with the mouse *does* bring up context menus in the limited user account, as well as in the built-in administrator account.

When running in Windows XP mode from my own account (I need this mode to run an application I use), the non-functioning right-click issue persists.

This problem arose seemingly “out of nowhere”. The only thing I had done recently was to run the “All tasks” (“mygodmode”) application–just as a matter of curiosity.


WHAT I HAVE TRIED:

1. I have run SFC. No change.

2. I have run checks for malware, viruses. No issues.

3. I have run ShellExView and ShellMnView. No change.

4. I have changed the USB ports into which the mouse and keyboard are connected. No change

5. I have updated the drivers for the mouse and keyboard. No change.

6. I have uninstalled, then reinstalled the drivers for the mouse and keyboard. No change.

7. I have tried a different mouse. No change (behavior is the same as with the Wireless Laser Mouse 5000 I use).

8. I have switched the left-right buttons on the mouse from the driver software/control panel. No change. It’s just the left-click that doesn’t work. Switching back to default takes me back to my problem. At least I know the issue is not in the mouse itself.

9. I turned off system restore and then back on again. No change. (I saw that this worked for someone else.)

10. Uninstalled “Mygodmode”. Reinstalled it. Uninstalled it again. No change at any time.

11. Disconnected the keyboard (in case of a conflict of some sort?). No change.

WHAT I WILL TRY NEXT:

I will connect a different keyboard (late tomorrow) to see if doing so has any effect.

WHAT I WOULD LIKE TO AVOID:

I’d prefer not to do a repair-reinstall, as I might not be able to reinstall Windows XP mode, which I use for a particular application.



I would appreciate any thoughts about how to resolve the issue I’m having.

Please take a look here and see if it applies.

Too bad. Thought I might have gotten lucky with that hit. There is something that disables right click because public library computers I've used have it disabled totally. Are you running any AutoHotkey programs in the task tray? If one has a bug it could "eat" the right click. I suspect it may be something like that because the keyboard menu key works.

You are quite welcome. Glad it's resolved.
