Saving for pop account settings isn't in yet. And this is also my first attempt at provxml's so may take a few revisions to get it right, sorry guys.
Other known issue for right now, when importing cabs some of the reg entries may not get double slashes "\\" in path strings. So far that has been the only cause of non-working rgu's for a while so we're getting closer
.
I'll try to have those 3 issues worked out by next version.
