Minimap not displaying correctly
 

I believe this problem began when I got the new update at Curse the other day. When full size, the map is as usual with all detail displaying correctly, as well as nodes, mailboxes, other things I've marked to show. But when reduced to minimap size and docked in the corner, it is a blur, as if it was zoomed all the way out. The zoom in and zoom out functions do not have any effect. The tiny inset map in the corner is displaying correctly, but the larger minimap doesn't show any map detail, it's just a blurry square. I've tried "restore map scale," and checked to make sure the Show options are correct. Any ideas? (Using v 5.05.06 on a MacBook Pro OS X 10.7.5)
