You must first select one or more messages

I’ve been running the 8.0.1 client for a sew months. Now, this morning when I have a message selected and I click on the folder icon to move it to a folder I get the error message below. I have made sure that I have a message selected. I have closed and restarted the Notes client, and restarted the entire computer. Does anyone know what would all of a sudden cause something like this?

Subject: Try replacing your design

Can you resolve the problem with a design replace?

Subject: RESOLVED

It seemed to resolve it with a compact of the local bookmark.nsf file.
