how to get the program to update itself

Every now and then the program calls home to see if a new version is available.
Then the alert form appears and it says do you want to update?
Obviously one would say Yes. However, at this point, the program would not update itself automatically, as like FireFox for example, but would offer to download the whole of the new version; as if you did not have a previous version installed.

This is a bit annoying, in otherwise an excellent program.

Suggestion: do the update behind the scene. See how FirteFox and oters go about this routine and follow that.
Thank you.

[I once tweaked the ini.file so that it would not offer this alert. But it seems that it has been overwritten: i.e., is a new ini file created evry time you open the program?]
