How to get rid of this totally annoying bug, which prevents me from transferring segments from TM to translation with shortcuts? No topics here helped, a new computer did not help, SSD disk did not help, resetting window layout does not help. The only thing I can do in this situation is to restart trados and then the bug reappears randomly. This is an absolutely terribleb bug in trados, it slows me down substatially!!! Can you tell me how to fix it?
