[omniORB] Problem with multithreading policy?

[Viktor Mikho]

Thanks for the prompt reply. I looked in the link provided but could not 
understand where do I get this "kludge" for 2.8.0. It is not in the 2.8.0 
bug/fixes list on the omniOrb site. Probably, the best option is to use 
3.0.0, however I am not sure if it still supports Win 95/98 (which I will 
probably need).

Thanks,
Vik
