Well I've finally got my track-ir- it works great.  I was using it to play rtcw and panning and all other features appeared to be working properly.  Now I seem to have a problem with that, the mouse pointer jumps all over the screen there appears to be no smoothing at all.  First I tried making changes to that game settings starting at it from scratch but have had no luck.  So, what have I changed in the configurations to cause this? I am currently using the latest version but it seemed to be working correctly on the old version. 
 
Any help or thoughts would be appreciated.  I am playing the game in mouse panning mode. 
for those of you that don't know, RTCW is Return to Castle Wolfenstein a FPS-

Re: RTCW
Could be a problem with IR interference.  Take a look in the Tracking window and make sure that the yellow box is locked onto your dot, not something else in the background, or jumping around.
