I just installed Zimbra Desktop and have set it up to work with my Yahoo email account. Everything was going grand and it was downloading all my emails to my computer. Now it seems to have stalled. The icon in the top left of the screen is moving which I gather means something is happening but no more mails are getting dowloaded. Every now and again a (1) appears beside Inbox in the folder tree to indicate a new email but then disappears again very quickly.
Any ideas of what's going on?
