Okay, next two questions:

1) Is there any way to make IE quit complaining about the HTA file? Every time I open the HTA file, it says "Do you want to open this from your current location, or do you want to save it to disk?" and doesn't let me turn off the prompting. I assume this is a security feature.

2) Some of the destination pages... The initial URL that we feed it works, even as a GET. OK, so far so good. But then they do some kind of a refresh or redirect/reload of the page that appears. The perfectly good formatted URL that I wanted to copy suddenly vanishes from the page's address bar, before I have a chance to grab it. Is there any way I can prevent this refresh from happening on the targeted page? For instance, disallow javascript on the NewWin we just created?
