I am running a registered copy of Build 3120. When I "Check for Updates" from the Help menu, I am told that my version is "up-to-date. How can this be when there have been 3 or 4 releases since 3120?
It has never worked for me either, well I have only used 3 of the beta releases so far but check for updates never found the last two and I just had to download them manually.
