[AGENT++] Access Violations on delete.

[Josh Pressnell]

Frank,

Yes.  That is also the example that I'm basing our MIB from.  One main 
difference is that we're running the agent within a CWinThread object 
which is started from a larger application.  I am also using a mib and 
request list which are local to that CWinThread object, rather than the 
globals from the example.  I tried using globals at one point, but that 
did not seem to help.

Is it possible there are issues running an agent within a CWinThread in 
an MFC project?

Also, I can browse and do GETs on the entire tree, but I can't seem to 
receive any of the traps I'm sending in MIB Explorer.  I'm searching 
through the manuals now... but any pointers you might provide would be 
greatly appreciated.

Thanks!

-Josh
