This behavior just started overnight. Everything was working fine last night. Now, I wake up this morning and ComicRack will not allow me to move pages within a comic. When I try, a little red circle with a slash through it appears and I cannot move the page. The files aren't read-only and I haven't made any changes to my preferences or anything that I am aware of. Rebooting and restarting ComicRack didn't help any.

Any ideas?

Thanks.

Usually this means they are no longer sorted by page.
