I-Pac and Aim-Trak Questions

[JZSlenker]

For the life of me I can't figure out how to un-map a shifted button on the I-Pac.  I want to remove the ` key from the shifted p1UP.  If I click on the button in the software I can change it to something else, but I'm assuming there is a way to just clear it. 

Question 1.  How do clear a shifted key in I-Pac

Question 2.  Has anyone had the following issue with Aim-Trak?    I have had aimtrak for a couple of months now.  It tested great and I installed it in a MP5 airsoft gun.  The LED emitters are behind 1/4" plexiglass that is not smoked.  It seems that now it is very hard to calibrate.   It just keeps going through the three screen position and not locking in the calibration.  Also it will just stop working periodically and need to be un-plugged and then plugged back in.  It works fine after it's plugged back in.

Question 2B.  Is the aim-trak effected by bright light.  My cabinet is set in my room such that the gun points somewhat towards my windows.  On a bright day it seems that the gun goes wacky.  I can certainly move my cabinet but was curious if anyone else had seen this.

Thanks in advance for your help.

To clear a button (either on the regular or shifted list), just right-click it and select "none."
Not sure about your other questions though.

Thanks, that worked.  How stupid of me not to try that.  The Aimtrak issue is easier to live with.
