Lost threads in VB-Com component
J?rn, you should read the guidelines in the VB documentation on the kinds of
care you should take when using various thread models. Circular references and
passing references to private objects spring to mind as potential sources of
problems. I suggest reading this material, which is under "Scalability and
Multithreading".
