I tried to look for the solution in the thread, but I may either look for the wrong keywords or whatever...

anyway, I can make the configuration stick anymore in my N900. Everytimg I set up MfE and close it after the sync, it forgets it's there and asks me to set it up again...

Anyone knows why and what I should delete? ( I tried removing .activesync and .qmf, but with no luck).

PS: my experience with MfE and Google summarized in this post: Synching your N900 with Google (Mail, Contacts, Calendar) with no third-party tools or service.
