Strange. I don't know what to make of that. But
the whole common block thing sounds like a red herring
to me.

Error prone!? I don't think of common blocks as error
prone. I think of them as "limiting in the context of
widget programs". I doubt the problem is with common
blocks, though. I'd be looking somewhere else. Where,
I'm not sure, since my knowledge of the whole system
is so limited. :-(

You may have to call in a professional consultant,
but be prepared to pay the big bucks. No one wants
to look at someone else's code. :-)

Cheers,

David
