Yesterday, I was working on some image stacks with some synchronized edits in Lightroom. The computer hangs up and I have to do a reset and the computer reboots. The only thing that was damaged was my Lightroom catalog and Lightroom would not open and the file could not be repaired. I tried various things which resulted in repair failure. So, I gave up on the issue and went to bed.
This morning, I examined a few things in Windows 10 that could trigger an operating system hangup. I just installed a Wacom tablet and the hangups were more common after this event. I changed a setting in Windows which prevents the computer from going into tablet mode. I ran the repair from Lightroom and everything has been fixed. There are some known memory problems with Wacom tablets so be wary of these issues and always backup your image catalogs before disaster strikes.
Happy Holidays to All…Jim
