[python-win32] Problem Automating IE on W7

[Jeff Peery]

Hello,
I'm using the code pasted below to print a document with internet explorer. The code worked great on my XP machine. I moved it to my W7 machine and it gives the error below. The weird thing is that it works great if printing a html doc from the web (such as www.google.com<http://www.google.com>), but it errors when printing a html doc from my desktop. The document loads (as I can see it on the screen) but it chokes when printing. Perhaps it is a problem with a new version of IE?

Any have a similar problem?

thanks,
Jeff
