Issue with Defined User function (in FW 7820)

[Arno K]

Hello Salvo,
I must admit that I had a similar problem with some cas-vars after the update, they had been fourier_an, fourier_bn and fourier_cn, their names were gone, the value (the program) still there, it were invalid objects, I could easily get rid of them on the calculator as well as in the emulator using SHIFT-mem and delete, as they had no name purge couldn't be used.
As I am very pragmatic I ususally believe in some of the rules by Murphy, on top of them: What can happen will happen. So I have not only backups of the contense of my prime and the virtual calc, each program file sits in a folder on my harddisk (and another copy on a micro-SD). So I have no problem doing a hard-reset.
Well, I think you can't easily manage this, as you are desperatedly looking for help. What about making copying all files from the calc to the ConnKit, hard-resetting the calc and then playing back the copied files one by one to see, which file was causing these Problems.
