It seems that the new accounts problem related above is gone.
In my frustration I made several changes at once, to vfs, menu, template
and reformated the "C" drive on the server computer.
Unfortunately, now I have no way to know what did the trick.
I can say that all features that I use in 237 are working as expected now.
Reading the forum posts it seems there have been a few unususal
and maybe difficult to reproduce anomalies lately. Maybe a "ghost"
in the system?
