Vlad,
Sometimes when I attempt to print a note, I receive an error message from AllMyNotes stating "An invalid argument was encountered". I receive the same error when I attempt to do a 'print preview' on the same file. I've tested several of my notes, and the problem seems to be related to notes that have long tables (i.e., longer than 1 page). To see whether the note itself was corrupted, I copied the contents of one 'problematic' note and then pasted it into a new note. The problem also occurred on the new note.
While I was testing several notes, a couple of notes (which also have long tables) caused AllMyNotes to hang when I selected 'print preview'. The point at which the screen would hang was always the same, within the print-preview window. The 'page count' in the lower left corner of the screen was always close to 5000, which is much larger than the actual notes, each of which were only a couple of pages in length.
