Could you send a library backup with unstackable stacks to matt at jriver? Include what files are in the locked stack.
Thanks.
The files are no longer a problem - I'm not sure how I cured it. I had previously tried quitting and restarting MC...but it didn't work - the stacked files were still locked up. Next I changed the Customized view but not as a troubleshooting tool. I was adding a field and editing TAG fields......
This morning was weird. I was scratching my head because a lot of editing I had done yesterday had disappeared. Then I realized my library had changed and I'm pretty sure I didn't do it. I changed it back to my regular library and that's when I noticed the stacked files were no longer stacked.
I've also had frequent MC27 lockups and crashes that I didn't have with MC 26.
Do you still want my library? I'm going to see if I can repeat the problem.
