This is an unsupported beta patch that should significantly reduce disconnects when running multiplayer races in GPL.  To use the patch... 

1) Download the gpldiscofix.exe program (~32Kbytes) and save it in your GPL folder (for example, c:\sierra\gpl). This program can be used to patch all versions of GPL 1.2.0.1.

2) Open a Windows Explorer and navigate to your GPL folder.

3) Make sure your gpl.exe program is writable (right click on the GPL program icon in your GPL folder, select "Properties", and make sure the "Read-only" box is _not_ checked).

4) Drag your GPL program (gpl.exe) onto the gpldiscofix program's icon. Make sure you drag the GPL program itself, and not a shortcut to the GPL program (a shortcut generally has a crooked arrow in the lower left).

That's it! You will notice that gpldiscofix has created a backup copy of your GPL program (gpl.exe_save).
