Running TB 78.3.1 32 bit on Windows 10 64 bit. Ever since I have upgraded to 78 I have had the same problem: unless I run in Safe Mode, the windows of folder (eg inbox, junk...) contents do not refresh when I select a different folder. If I move the mouse pointer over the window contents, then the relevant lines that the mouse pointer is over are revealed, but not otherwise. This still happens when add-ons (which I don't actually have many of - only add-on is a dictionary) are disabled. Only Safe Mode fixes it. Any suggestions for how to fix this? I have already reset toolbars and controls - no difference Thanks
