[Ace-users] Proactor on WIN32 with multiprocessor Xeon - anyonegot this working?

[Chris]

Hi Alex,

I have now started building my code more around the Proactor code used
in JAWS rather than Proactor_Test, and have been very pleased with the
outcome.
I will certainly take the steps that you recommend during shutdown,

Many thanks,

Chris.
