- changed the place where the CheckRequireMouse event gets called.

Browse source 
The original place in I_CheckNativeMouse is unsafe because that function can get called from the system message queue which can result in a bad global state of the VM for such a call because it can be recursively invoked from code that may temporarily alter some settings.
