I cannot isolate to any particular program or app, or home or cas. I've had it happen in all places, thus sometimes losing significant work while entering a system of equations in cas or creating or editing a user program. The only commonality is that it always seems to happen after a keypress, but no particular key. Makes me want to turn the calc off after every line I enter so it gets saved to flash.

I have tried the F,C,O, reboot, reformat disk, etc, etc
Tried different usb ports to update firmware,blah,blah
Kept things as vanilla as possible to whittle down possibilities...

I thought things like this would be sorted after 4-5 years, guess I was wrong. Can't imagine what early adopters were dealing with. Might just try a return to seller. Shame really, since I've probably put in 10-20 hours learning the thing (it's new). My hardware is C, but it's got the darker colored blue.

I'm having the same issue, as I mentioned earlier up above. Having used the calculator a lot since then, I have determined (like you) that the only common factor is that it occurs during or immediately after a key-press.

Like you, I've also tried various manners of rebooting/restarting, etc. I've taken to powering off/on frequently for the time being. I think the HP Prime is an excellent calculator otherwise so I'm very reluctant to give up on finding a solution.
