I had Photomechanic 5 Build V5 build 17146 It refuses to upload to Photoshelter as described on another thread. I followed the advice and link installing Photomechanic 5 Build V5 build 16765. This hasn't cured the original problem it has just added a new one Thumbnails now randomly flash on and off the screen if I click to see a large version that also flashes on and off. I have to shut down and relaunch the program to stop this behaviour... What on earth is happening to Photomechanic?
