Creating MSHTML::TxtRange Object Causes Function to Exit w/o Excep

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hello,

Has anybody encountered an interop situation where calling a COM function
will cause your C# function to simply exit without throwing any exception,
and without executing any code beyond where you called the COM function?

I am trying to create a TxtRange object on a Selection Object like thus:

SelObj = m_Document.selection;
TxtRange = (IHTMLTxtRange)SelObj.createRange();

And when it hits the line where it should create the TxtRange, it simply
stops executing code inside my function and exits the function without
throwing any exception!

Can anyone shed any light on this behavior for me?

Thanks a lot,
Rich
