ok lately ive had this problem on steam and on steam only where my mouse will be working fine then a new round will start and my mouse wont work, then i die ofcourse and a new rpund starts and everything is fine again, anyone have any idea what the problem is and how i can fix it

Try hitting escape twice when it breaks and see if that works.

are you using a wireless mouse ?? that can very well be your problem

no its not a wireless mouse, its a usb port mouse

Is it a ball or optical mouse? And how old is it?

Kind of like my keyboard sometimes it want go foward at the beggning of the round so I have to move over then go........Or it locks sometimes when I'm dead.

I had that problem before with the logitech "Wheel Mouse Optical", it was because my brother had spilled something in it, and i had to unplug and plug it back in for it to work for 20 more seconds..it was wierd cuz it only happend "ingame" and never while browsing any websites. I just said screw it and bought a new one, im using a logitech mx510 atm. Its great :D

My brother uses a wireless mouse with batteries and he has to recharges the batteries like every month. I use the Microsoft Intellimouse and i had it for over 5 years and its great i would never buy a wireless mouse.

its opticle and its maybe a month old but this only happens when i play cs, never when im doing other things
