I tried running compiled versions and in the IDE and stepping through the code - because I couldn't make much sense of your message.
As I said, I encountered no problems/errors/exceptions - so didn't bother responding, then. There are known "issues" when debugging under a 64 bit O/S, but I don't know if that would cause your problem... http://blog.paulbetts.org/index.php/2010/07/20/the-case-of-the-disappearing-onload-exception-user-mode-callback-exceptions-in-x64/ On Wed, Apr 27, 2011 at 1:35 PM, Scott Baldwin <carpenoctur...@gmail.com>wrote: > Jason, the problem is that when running in Visual Studio 2010 in debug > mode, it throws COM Exceptions, whereas it did no such thing in Visual > Studio 2008.
