It seems like every other month my HP 39gii gets stuck. I try the reset procedure (ON+F3), take the batteries out and re-insert them, but to no avail. The calculator gets stuck on the loading screen and just stays there.
The HP 39gii ROM needs an update. I am not always near my computer to have to reload the ROM (and reprogram the lost programs).
This and the CASE command that does nothing is what makes a rather nice calculator frustrating to use. As a result, I was planning a programming series on my blog - but I am going to have to either delay or cancel it.
Thanks for your patience.
