Can't see DLL symbols in debugger.

Hi. I have made a small test program consisting of one application
and two DLL's. Each of the three components uses the services of the
other two.

The program works great, but I can't see see dynlib1's symbols when
I'm in applic, for instance. Then when I'm in dynlib1, I can't see
applic's symbols. The program works, so the symbols are there, but I
get a message in the watch window like CXX017: Error: symbol
"dynlib1_datum" not found.

Surely this isn't how it's supposed to work. Now that I've boiled it
down to a few lines, can someone show me the magic key? Or perhaps Visual
Studio has a bug?

Regards, Rick

Dynlib2 is similar to dynlib1.
