GTA3 - Multi-monitor mouse issue persistent

[triptemp]

I got GTA3 from Steam. I'm running it on 64 bit Windows 7. I've got 2 monitors; the primary monitor is widescreen and the secondary monitor is normal (4:3).

 

The mouse cursor isn't sticking with the widescreen monitor on which GTA3 is running (full screen), so whenever I click when the cursor is in the other monitor, GTA 3 minimizes. This appears to be a common problem.

 

I've tried SwapScreen and UltraMon. Both of those apps lets me lock the mouse to one monitor when GTA3 is not running, but as soon as GTA3 starts, the locking stops working, allowing the mouse to move back and forth between both monitors. As soon as I close GTA3, the locking works again.

 

I've tried bonding to different key combos, but got the same behavior.

 

So, for some reason when GTA3 runs, the mouse locking programs no longer work.

 

Is there a way to get SwapScreen or UltraMon to work correctly with GTA3?

 

Thanks!
