Dont understand...
I have tried both this and Crystal Calc both by same author and have had no issues at all. It is possible the glitches dont show for some time, but, as I said, no issues. Maybe it has to do with what I-device it runs on. I have iPod.
Love the tape, snazzy backdrop, cool little calculator.
