I installed the community patch version 3.1 and everything seems to work except the mouse does nothing. Mouselook doesn't work and neither do the mouse buttons. If there's no solution to this problem I guess I could just set it up to use keyboard only but mouselook would be nice. Thanks.

Make sure you've set all the options during patch installation correctly and also make sure you don't have another "Killing Time" folder inside your Killing Time game folder after patch installation. If that folder exists the path set during installation was not set correctly.

Ok thanks. In install options under "controls" I have "Full mouselook" checked. I do not have another "Killing Time" folder inside my Killing Time folder. One would think that having "Full mouselook" checked would set it so you use keyboard for movement and mouse for looking around. What do you think?

Ok I got it working! Thanks for helping. I deleted the game in GOG galaxy but I didn't delete the patch files. So I deleted the game again and deleted the patch files. I installed the game again and installed the patch and all is well. Cool! I really enjoy the game and am glad I could get it working.
