erratic cursor again

Post by Alden » Tue Aug 13, 2013 7:20 am

I've been using SmartNav for years in the same room, same location, same type of painters hat with newer dots. Computers have changed as well as Windows from W95 to Win7.
I have recently experienced erratic cursor activity due to ir reflecting off me. I shut the blinds. I'm unable to increase light filtering anymore. SmartNav will only work when a cloud blocks the sun or late in the afternoon and evening. It seems camera sensitivity has increased. Even an incandescent lamp off to the side now produces too much ir. Things worked perfectly a month ago. I did change to build 39 final. I have also noticed the green led on the camera no longer is on when tracking. I'm baffled.

I have started getting the same erratic behavior it's like there is a small light reflection where the green dot stays on. The status keeps jumping between tracking and no data.
Were you able to fix Aldens' problem or should I submit a ticket?
