Well then please send the files. All the ones I have, and those in our test cycles do not exhbit any issues.

You may try with this unlisted document :

Here is a way which does reproduce the problem in all cases on my HW-C calculator :
- reset
- load the 5 first files : test01.hpprgm to test05.hpprgm
- reset to clear the RAM
- press Shift+Mem
- press Shift+Program
=> with firmware 10077, several programs just got destroyed (truncated to 0.23KB)
No such problem with firmware 8151.

I am also able to get similar data corruptions without even opening the memory screen, just by launching the programs, except that it's random (have to do it several times in a row and things like this...).
Maybe I've been lucky, but this never happened to me with the previous firmwares.
