COM and CreateObject and inheritence

[tiddlerdeja at my-deja.com]

I've now used the VB debugger and found that I get 99 returned from my
function bar:

x = c.bar

x now contains 99.

If I try to do anything with x:

MsgBox x

Then VB crashes.

My COM object seems to work fine from Python and Dispatch calls? Are
there other tests I could do to diagnose the problem? Could my
installation of VB be broken?

Any help apprecuated.
