For those getting mouse bugs, only solution that worked for me easily

Okay, so for those who gets mouse and keyboard locks, here's a solution that I just tried and it worked. So first of all you will do Alt-Control-Delete to get to your Task manager, and you will go in Processus.

Then, you are going to look for crossfire.exe and right-click it
NOTE: You have to do it everytime you open your game

After that, you should see Set priority or something like that, you go on that and there will be priority levels as Normal, Superior than normal, Etc.

You want to get the priority lower. So you either click on lower than normal or simply lower.

So remember, do it everytime you get on CrossFire.

Sorry if some words are not correct I'm actually from Quebec ( so im French ), so are my computer settings.

Hope this helps
