I've been running Miranda for a few days at home and really enjoying the simplicity and lack of horrible popups.
I've got a 512MB USB flash drive (this one, if anyone's wondering: http://sandisk.com/retail/cruzer-mini.asp). I use it to run Portable Firefox in defiance of corporate policy. :) I thought it might be fun to run Miranda off of it, as well. I installed it at home and had no problem getting it to work with my laptop and wifi.
When I tried today at work, however, no luck. No amount of choosing Status > Online will convince it that I'm online, and all my AIM buddies are ghosted because I'm not connected. (It's not plausible that they all happen to be offline at once...some of them always leave it on.)
Am I doing something wrong? Or do you think there's something about our corporate internet setup that's defeating me? (Obviously, I can't affect that.) I'd appreciate any tips, although I'll certainly understand if this strange thing I'm trying to do isn't a supported feature.
