I have the same problem with a Logitech G5 mouse with AND without the setpoint drivers. When i start the game the i get no error message, the pointer is just invisible. But only in full screen. In window mode the pointer Is visible (swith to software mode?)
After i connected a Microsoft mouse and installed the drivers i now can see the mosuepointer in full screen mode and i can even use the logitech mouse.
But i dont know wether the pointer mode switched to software mode after setting off full screen mode and activating it again.
My graphics crad is a NVidia GeForce GTX 285. but i guess that the problem is the Logitech hardware.
have tried both hotfixes for this isue and while yes the /softwarecursor 1 does work temporarily i have to enter it any time i hold and drag to adjust the camera. is there a fix that will fix it permanatly or do i need to do something else
