ERROR: COM object that has been separated from its underlying RCW can not be used.

I keep getting this error on this line of code:

code:
IXMLDOMNode tripToNode = mainDOM.selectSingleNode("//my:TripToDate");

Any ideas of what could cause this? The field i'm changing in the form is a
date field and it's hooked up to a OnAfterChange handler.

Mike Surface was getting this error this morning. Steve replied. Have you
had a look at that thread?

Didn't see the thread until after I posted. Sorry.

I did Google on it. The relevant MS KB article refers to the error in the
context of server-side web programming and came out in June of 2003. The
hotfix it references was supposed to be rolled into the .NET Framework 1.1
(which I'm using.)

I'm not sure how any of this relates to InfoPath however.
