Years ago I reported a bug that it"s still there:
While saving buffer to disk The last saved address for 4Mbit devices should be 7FFFF and not 80000
[because otherwise you are saving a bigger than 512KByte obj]
Currently we need to correct this manually each time we save data

Yes, it"s a very obvious thing, but it should be corrected

example: it happens while reading any serial flash eprom. For instance: 25X40

Thanks in advance

Best regards
