epinety, dscobsct: there may be a problem somewhere concerning the fact that only the first sync works in the two directions. I will investigate it further to see if there's a pattern.

epinety: thank you for the stack trace you sent me. In fact it showed that there's a bug (not related with the non-sync of events) in the code that needs fixing.

In other news, I've started to fix the issues all of you reported in the last few post. Keep those report coming: they are really useful! Further enhancements are also in the works, so stay tuned
