[omniORB] Using an omniORB client with an Excel add-in

[Sai-Lai Lo]

This is a known problem. A long answer can be found in:

A short one is to add the option "-ORBoutConScanPeriod 0" to ORB_init.
Or add this call before calling ORB_init():

    omniORB::idleConnectionScanPeriod(omniORB::idleOutgoing,0);

Please let the list know if this solves your problem.
