Interesting that none of the Delta Force Games (I just purchased them all) work at all on my PC. Some will come up, but mouse does not work.

However, using my MAC and Wineskin they all run perfectly....but I purchased them to rum on PC.

Sorry to hear that. I got only DF1, 2 & 5 and so far played just 1, which is working fine for me (i7-6600k, AMD RX 480, Win 8.1).

I'd suggest doing a little debugging. Check your df.cfg file in the install folder and see what you have under CONTROLS. I have:

// CONTROLS
flipmouse = 0
crosshairs = 1
mousescale = 137
showgun = 1
picinpic = 0


Edit: tried them all just to see if they work and DF1, 2 and 5 work fine for me.
