There's a little problem with the LJ-cut command. I used the key-command to bring it up, and think I accidentally hit Command-K-L, but the sheet popped out, no problem. I typed in a text, and hit 'OK' The tags were inserted, but the sheet didn't go away. 'Cancel' didn't work; neither did 'OK' both with text and without. (It did insert more tags, however.) If this is a known issue, sorry.

EDIT: Submitting the entry via the menu command worked, but the cut menu is still there. If anyone else has this problem, submit via the menu command and edit it later.
