When you double click on the "family name from the left list column" in the "Matches" portion of the program, it brings up the associated matches. If you find matches to your database, why can't you update your file without having to do it manually. I think you should be able to click on a person in the "matches files" and you should be able to update the same file in your database which is listed as the first file in the matches program.
Yeah, I thought that at first also, then I found some matches with glaring errors, and if you didn't know there were errors you would be putting errors onto your tree, so I wouldn't want to download, I just copy out on paper.
