Seriously doubt it's a hosted mode mode issue.  Which browser did you test
web-mode with?  Hosted mode actually launches a version of IE6, so using FF
or IE7 may present different issues (for instance they might have a raised
AJAX connection limit)

The issue is purely on the client side.  Are you calling getEvents (the one
that sends of the request to the server) on the client-side more than once?
