That's not a skin problem, I guess. Before giving up, try to replace the skin (to Plain) in the jalbum-settings.jap file to see if that fixes it. If not, you can still exclude objects in the .jalbum/albumfiles.txt file by adding a minus sign before their names. (You might need to enable "Show hidden files and folders" on the Explorer's "Options / View" panel.)
Yes, I dithered about whether it was a Skin problem.
Without doing the above, it mysteriously started working without freezing with the problematic LEGS Album. BTW - It is the largest Album I have by far, compared to the others, which might have been a factor causing it to freeze.
Just out of interest, I screenshot the Task Manager whilst it froze and it shows a very high memory use! The black part above the Task Manager is the frozen jAlbum Interface! (see attachment)
I'll close this post down as Completed and hope that it doesn't occur again!
BTW I'm using a very new Windows 11 PC.
