Erroneous post:
I had the problem solved by post #382 earlier. Now I 'm getting a different failure.

DropN900 runs normally, claiming to up and download appropriate files, but my dropbox files are not updated. If I use different PCs Dropbox works fine. If I re-open DropN900, it offers to re-up/down load the same files.

Any suggestions?

My bad,

either the edits reverted or my .config was reverted. I re-did (undid?) the edits from post #382 and it's working.
