Hi everyone,
I have a rather bizzare problem with my STALKER game. While in movement, my gun won't start shooting unless I hit left mouse button multiple times like crazy. If I am not in movement, the first "click" of mouse never shoots but the second does.

Any ideas how to solve the problem?
Thanks guys for help

I have no idea, is it with every gun?
Can you check the condition of the gun, a lot of weapons you pick up from dead enemies are in a bad state.
