Problems I have detected while using, or attempting to use this:
Menu Bar frequently disappears, causing me to Alt-F4 it and start it again.
Wont save settings most of the time, even when run as Administrator, though that does seem to increase the chance of settings saving.
The Auto Calibration will go up to 200, then 208, then 200, and so forth despite the fact that it is NOT subtracting... IE there hasnt been a trigger to cause the sensitivity to go down, yet it reverts back to 200, a test I did was to set the up and down to 4, it still went to 208 then back to 200. I am not sure if that is perhaps a calibration cap.
There should be an option to do a quick calibrate.
Otherwise, when it has worked for me it worked very well. Oh and it doesn't work well when there is a reflection on the water, and wont work at all in Moonglade.
Really like your work!
