Re: Re: Getting mouse click info form a non Gui4Cli window.

Since you are filtering the mousemove messages and using only the mouse
clicks, you shouldn't have any noticeable delay. The system is way too fast
to be slowed down by such stuff.

From what I see you are not handling the nCode value and calling
CallNextHookEx() if its negative, etc..

Maybe that's the problem.
