Thanks for replying Stan. I got it working again after re-downloading the WebBuilder package and moving it to another location on my machine (and a few reboots).
I appreciate you trying to help. Everything seems to be working normally again now so I cannot capture any screenshots. Here is a desciption of what I was seeing - a blank panel for templates (neither of the built-in templates appearing) and a blank panel for the in-panel widgets - Other than that, everything seemed okay. Something obviously got fowled up.
thanks again,
Mike
