imap in Mail not working like others

[martyrk]

I am running IMAP in all 3 of my macs I access using Mail.app. The first two (call there 1 and 2) macs are running 10.4 and the issue I am having is with the third (call this 3) mac which is running 10.5. Heres the scenario

When I access a new message on computer 1 or 2, it marks it read on that computer, and then marks it read on the other 1 or 2 computer, but it never marks it read on the mac 3. If I access a new message on mac 3, it DOES mark it read on all macs. Is there a setting I have missed with mac 3?

Thanks in Advanced

That is very odd as it should be syncing the read/unread status. Are you checking mail on Mac 3 after you mark the mail read on one of the other two? Because it won't update the messages status to read until it does a mail sync.

If it is checking and not updating, then I am at a loss as to why it would work that way.

Yes I do check the mail on mac 3 after I read the New message from mac 1 or 2 and it still shows up as New message
