I may know what's up:  If you define instances of your class in the 
header file:

<foo.h>

Myclass Foo1;

Every file that includes foo.h will make a copy of Foo1, and a virtual 
table to match.  Make sure all data declared in the header files is 
"extern".  Then define the actual instance in one of your modules.

{ This isn't a clear example - anyone care to summise the problems of
  inlines/templates and vtbl emmision ?? -mod}
