Thank you for another smooth update!
One feature of the update is that CPU clock is switched when powered by USB.
I made a speed test (the same as in this post: viewtopic.php?f=33&t=3537 ).
Result: 3 seconds with USB power supply compared to 8 on battery.
Impressive!

I agree. But the question remains: Why could it not be solved by HP 50g, which has a CAS integrated, and by HP Prime in CAS Mode?This integral is trivial for a CAS.

Re: How to load .pgm files?
With DM32 you cannot load or save single programs but only complete states.

I am not talking about WP43 but about DM32.looking at the menu in WP43 EQN you'd find two arrows at its wings which do what you want, don't they?
