Every time I try to edit a certificate, the application disappears, and goes to the background. When I try to bring it back forward, it resets to the start screen, essentially crashing. Also, when I create one one certificate, I'd like to create copies of it for each kid, but the applications forgets any changes I made to the signature and to the seal, although it does remember the kid's name and the date. I'm using the very first certificate. Also, I basically provided a blank for the signature (instead of actually scrawling in a signature in the entry field) so that my teachers could sign the certificates later. It would be nice to be offered a blank signature as an option.
