Especially with longer files.
However, I have found that e-notes do seem to work properly if you give them enough time to save the notes.
Saving a note is not as easy as it looks. It says 'note saved' but what it really means is, hey we started the save process and it's going to take a few minutes. Your data will still be available I think, as it's temporarily stored on the e-note, but things like printing and deleting and some other stuff wont work properly and will throw the e-note out of wack if you try to do them before the file is actually saved.
So when you add a new note.. wait a minimum of 5 minutes before trying to do ANYTHING with it. This may prevent data loss as well as some other problems. At least until we can take a hard look at the code.
I'd suggest doing a few test prints to make sure it looks okay before printing 10 copies or whatever, but with the state of the code I suppose that might not be a good idea. XD
