Eww.. Waste of CPU time. I suggest using the Win32 API Sleep or _sleep 
functions instead. The reason is that your above delay function is 
constantly working the CPU as it goes through the loop. The Sleep or_sleep 
functions on the otherhand will actually halt the program until the set 
amount of time has passed.
