Apparently the version of CnCNet 5 included in the patch didn't work... so I fixed that.
Additionally, I've been informed various times that the game has a bug where the mouse freezes when you open the in-game menu. I knew that the fix to this was to enable Win95 compatibility mode, but unfortunately, the config tool removed compatibility if CnC-DDraw was enabled, because that's the way it worked best on WinXP (on which the patch was originally developed).
That has been fixed too now; the tool should now set the appropriate compatibility mode for every situation.
Nice work. :)
