An outgoing call cannot be made since the application is dispatching an input-synchronous call

I get the following message "An outgoing call cannot be made since the
application is dispatching an input-synchronous call"

When this happens, my application is calling an in-process COM object
that in turn is trying to access an out of process COM object.

App --> Inproc Com Obj --> Outproc Com Obj

Does anybody know why ?

"Automation clients are required by COM to process
input-synchronous calls without interruption, and therefore
are prevented from making outgoing Automation calls while
processing such messages."

The usual workaround is to post a Win32 message, and have
your COM object handle that message.
