In principle this is a good utility. When it worked it was very quick and feature rich. However, there were major problems on my machine as I would frequently get messages that the Winpopup message box was in use by another program (it wasn't) and I'd get a dreaded blue-screen VD driver conflict at other times. I spent a couple of hours, and lots of reinstalls, reboots, and registry checks but couldn't get it stable... a BIG problem when you want to convince coworkers to try it out.
