Greetings!

I found the same scenario in my workplace. Unfortunately, I think this is pretty common.

I usually open a DOS (CMD) Window and

set HTTP_proxy_pass=firewallpassword
[download]

before kicking off ppm within the same window. Note that I already have HTTP_proxy and HTTP_proxy_user set up in my environment. I felt uncomfortable putting any password in a file like this. I agree that a quick Perl/Tk application to prompt the user and kick off PPM would work nicely in this situation.
