HP Prime programming problem: PRINT command stops working

[Jenab6]

I was programming an orbit determination code into my HP Prime. It uses the method of Gauss to find orbital elements using angle-only input for the other planet and heliocentric position vectors for Earth.

Anyway, I was debugging by doing PRINT output after every block of calculations, to make sure that my answers matched the ones in a book I'm using. After about line 160, the print command stopped working. It didn't throw an error, but it wouldn't execute, either. I got a last line of output from a program run, and then after that line none of the later Print lines did anything.

Is this a known bug? Is there a way to fix it?
