Thank you so much! This solves the mystery because I always have loaded the new apps from my desktop and then moved the files into another folder for long-term storage. Guess I confused application loader.
But I gotta say that I think this is poor software design. A better way would be for Application Loader to look at what's on the BB and assume you want it there, regardless of files remaining on the pc. Go Figure.
Anyhow, I sincerely appreciate your help in this matter.
