A problem that just started after a support contact related to subscription difficulties and then LR thinking that another LR catalog was open. Cursor control of crop frame is unstable. When attempting to drag a corner, the crop window disappears and the cursor is creating a zoom effect. Holding the mouse button down causes the zoom to shoot in and out. Makes cropping all but impossible. Zooming and zoom window control in the X Y function of Library is similarly affected. I have used LR since LR3 and have 20+K images in my catalogs so I do know how the functions should work. I am using Windows 8.1 and have been for a year or so. The problem seems to be getting worse by the day. My last support contact took over my screen and installed LR updates that I had been staying away from since things were working OK. I am now running 2015.3 Release, Camera Raw 9.3. Deal almost exclusively with Nikon NEF files, though I was converting them all to DNG until the last tech support suggested things would run faster (better ?) if I just stayed in NEF. Any suggestions would be appreciated. I am not terribly computer savvy, so system changes like rolling back to an earlier version are not easy for me. Tom
It sounds as if your mouse is dying. Try another one and see if that fixes the problem.
I have to say, my first thought was "How likely is that when the cursor still runs around where I tell it to go? Still, I went to the hole where all the old mice reside, picked out a likely suspect and lo and behold - it seems that the problem may be solved. I'll get back here if that is not the case. Thanks for your prompt reply. Saves me a long time on the support lines, even supposing that they were not closed for the next two days. Tom
