Thanks again for all the help Bernd, I sincerely appreciate what you've done to get me back going.
Bottom line is: I am back working 100% with a much better understanding of how everything is pieced together now.
That was my hidden intention ;-)
BTW: Did you notice the apologies from MS and the deletion of the advice you were the victim of ?
Some further comments:
"Personal (Web)" is a generated and fixed name on Skydrive. The app needs it.
Never use Dropbox for synching of Onenote notebooks. They use different and colliding synch mechanisms. Said that I am a convinced Dropbox user too, for any other file type.
Onenote makes backups automatically which are always local at any computer where the Onenote desktop SW is installed. For open notebooks only.
Never close a notebook because this deletes its copy within the cache.
Thanks for the cup of coffee, would be a long way, because I live in Germany, near Munich.
Bernd
