I've been using Sergey's cdo2000.prg for some time now and it works great.

Recently, however, I've started encountering random hangs. I added some logging code to figure out exactly where it was hanging and it's at:

this.oMsg.SEND()

The same computer will send hundreds of emails fine and then, for no discernible reason, it hangs at this line.

The default timeout is 30 seconds but the hang is not releasing; my application has to be end-tasked.

Any ideas?
