With Show pre-release versions checked, the installed version is 1.90h[b].019 and the available version is -----.
i believe that should mean you have installed the latest beta
With Show pre-release versions unchecked, the installed version is 1.90h[b].019 and the available version is 1.90.026. There is no letter in the new version number. Nor is there a [b] or [beta] reference in the new version number shown.
released versions shouldn't be showing beta reverence in the version number
example
i currently have object bar [beta] 2.10f[b].011 installed with 2.10f[b].012 dated 8/23/2007 showing as available with 'show pre-release' checked
with it unchecked I show 2.00.009 dated 9/21/2006 as available
if you have "----------" showing as available, it means you have installed the latest beta or released version, depending on which you have installed and whether pre-release is checked.
I see that my installed version is 1.90[b].019, and, with "show pre-release varsions" selected, the available version is ----------.
according to SDC you have the latest beta installed, no newer version available yet
If I then deselect "show pre-release versions" I have the same information regarding my installed version (as I would expect), but now the available version is 1.90.026.
according to SDC that the latest released version (non beta) available to you
you can also check the dates to see which is newest
with "----------" showing as available, the date shows the date of the version you have installed. if a version shows then the date is the date of the version available
I don't have plus, but I'm guessing 1.90.026 has a newer date than the beta
