Version update failed

Hello,
updating glyphs on my notebook (MacOS 10.8) fails since you released 1.3.17. The dialogue tells me that 1.3.17 is currently the newest version. Today my other Mac (10.6 or 10.7) got 1.3.19.
What am I doing wrong with the macbook?
cheers

The version 1.3.19 is only shown, if you check “Show cutting edge versions” in the preferences.

thanks!
