Kind of interesting, when I do auto trace it works fine, when in manual, I enlarge the image small parts are easily selected, larger parts are harder and some can't be selected. Something I noticed, correct me if I am wrong, when manually selecting, the point you selected, is where the laser will start its burn, so I try and keep the points in close proximity. I replaced the old laptop with a new squeaky clean one, that is dedicated to just laser, T2 and BCL. The only time it goes online is for updates. So the issue must be me!! I'll figure it out, I always do, maybe not always the most sophisticated way but it gets results.
Thank You for your help
