It's been awhile since I created a metal blind so that's what inspired me to 'hammer' this one out for your viewing pleasure. It's extremely lightweight (231k w/wallpapers!), was build with everyday usability in mind and I've used it myself the past couple of weeks with no conflicts or 'weirdness' at all when using other apps (Firefox, Office, etc.). As with all my recent blinds, XP and Vista / Win7 versions are included and they’re all thoroughly skinned. Give Patriot a try...I really do think you'll be pleased with it!
