Checksum feature seems broken on MPLAB X IPE v5.30
I'm using MPLAB X IPE v5.30 and it seems like the checksum feature on the screen does not work. The first time I load a HEX file it shows a number, then I change the HEX file and reload it and the 32 bit checksum does not change. Interestingly, the 64 bit CRC does change. The checksum is a more convenient number for me to use. Is there a way to get it to update, or am I missing something basic? If it matters I'm using it with a PM3 programmer, but that's not involved in loading the file into IPE.
