GMail Problem

Anyone else having this problem with their Gmail account and is there a fix?

Gmail is telling me that I have 1 unread email eventhough all are actually read.
I've done the "select all unread and mark as read" thing but its still there.
Its not causing a huge problem it more annoying than anything
If someone has a fix, I would appreciate it.
Thanks

Simple fix, don't use the horrid gmail site, download your gmail messages via client software
