Prime Totally Hangs

[Helge Gabert]

I'm curious if anybody else experienced serious freezes (with the current firmware).

Last night, my unit wouldn't switch over to CAS mode anymore - - hit the CAS button, and the hourglass came on. Neither On-Symb, nor On-Esc-Apps worked, and the Prime didn't turn off.

A paperclip reset did the job - - however, all my CAS programs are gone, also functions stored with "Define", all global variables, custom apps, and Home and CAS settings - - gone. PPL programs, however, are unaffected.

I believe that memory was corrupted, perhaps because the three "recursive" settings in the CAS settings (2nd page) have default values which are too low; but that is only a hunch. I set them to higher values (50), and so far, touch wood!
