Recently Sparrow (my favourite email app by far) started crashing after a few minutes. Due to this and the fact that it won't be supported for much longer I decided to give Postbox a try. Liked it and bought it. However, one thing (okay, several more, but that is a different matter) is bothering me: When I move/copy/archive messages on my GMail account, they only get sorted for real after I close Postbox. As the computer is only restarted every few months and I have the email client running all the time, this does not happen very often, which leads to problems if I access the mailbox via the web interface, where all these moved/archived mails still appear in the inbox. Is there some way to have Postbox make changes to the inbox instant?
