yes yes - I am using the remote gallery on both the mac and the pc - without any problems.
Thanks for the credentials. We were able to reproduce the problem on our end and have added a workaround for version 4.6.2 of Photo Mechanic (in development now). The issue is that you have a couple of galleries with zero-length names (effectively they have no name.) We reported that as an error. With our workaround in place we substitute a title of 'Untitled', 'Untitled (2)', etc.
You could workaround this yourself by giving those blank albums a name and then Photo Mechanic 4.6.1 should work fine for you on your Gallery2 installation.
