Thanks for the input, Mike. Since I don't have much experience w/
either, I don't have a strong preference for COM over PAMIE. I'm just
frustrated my script isn't working. I guess it could have to do w/
privileges. I'm using a VPN connection. I tried turning off my
antivirus software before running the module. I can click on the
button I want manually, and get the page I need, so I wonder if I can
adjust some settings to allow Python to take control of certain
things? That or I thought it might have to do w/ a javascript error.
By looking at the tag, does 'PDF Preview' look like the name of the
button or the button caption? Let me know what you think.
