Mouse freezes in game

[StepanKo]

Hello. Yesterday all went good and I played this game without any bugs\lags\etc. But today, after I joined the game, my cursor freezes and don't response. What i need to do? I found many ways to solve this problem but i didn't help me.
If it can help, I have license copy.

Искал решение этой проблемы я очень долго, но до сих пор не смог найти решения. Помогите, пожалуйста. На этом же форуме была похожая тема, но она мне не помогла, без понятия почему.

I don't have this problem anymore.
So, help cerp, please.

I'm also having this problem. Yesterday I played 1.2 perfectly. Today I altered my settings (turned them up to high, raised AA level) and now when I join the game, the mouse is frozen in the center of the screen. When I hit escape and go to the menu the mouse is working perfectly fine again but only in the menu.

I'm having this issue as well, no idea what's causing it.
