WTF is wrong with Gmail & Mail.app (IMAP)?

I recently set up Mail.app for Gmail using IMAP. Since then I've noticed that my inbox in Mail.app and in Gmail on the web is always out of sync. For example, I have one message listed in my inbox in Mail.app right now, and there are eight still in the inbox in Gmail. Also, I have several folders in Mail.app (corresponding to labels in Gmail). When I move a message from the inbox in Mail.app to one of these folders, and then try searching for it 30 minutes later, it doesn't appear in the folder or anywhere in Mail.app. If I go to Gmail on the web an search for it, however, it shows up there.

The irony of it all is that I finally decided not to renew my MobileMe subscription and switch over to Gmail. I'm beginning to regret that decision.

Is anyone else having these problems? If not, maybe it has something to do with my configuration?

 

Good question

Every 15 minutes. So it will only be syncing every 15 minutes, I guess? Duh.

 

How long does it normally take to sync in your experience? I just changed Mail to check every minute. Then I hit the "check for new mail" button on the toolbar. I would think that would sync Mail.app and Gmail. I go to Gmail and there are still many more messages in my inbox there than there are in Mail.

 

I guess a better question is, how long does it take for a message that you delete (or Archive) from Mail to clear out of you inbox in Gmail? I don't have a problem with new messages coming in, but if I move a message from my inbox to another mailbox in Mail.app (which has the effect of archiving it and adding a label in Gmail), or if I delete a message from Mail.app, it hangs around in my inbox for a while.
