Multi-Monitor Cursor Trap Fix

[milo christiansen]

Just in case no one noticed trapping the cursor on the primary monitor of a multi-monitor computer is broken in the latest masters. This really does a number on edge scrolling so I decided to share a AutoIt script I made a long time ago to solve similar problems in other games.

This script will likely need to be modified to work on your system. I added a few comments indicating the interesting spots.

Does AuotIt need to be installed to use this script? or does it just need to be saved as a certain file type?

Did you add a keystroke to end the script? I can't tell from the code above

Yes and no

Yes, AutoIt needs to be installed, or you need a copy of autoit.exe at least. If you have Autoit installed then make sure the file is saved as a ".au3" file.

No, I did not add a hot-key and I don't plan to. If you want a hot-key look up... hotkeyset I think... in the AutoIt docs. Its a simple mod that would require minimal knowledge of AutoIt to add.
