I can imagine it would be! But like I was saying, it could be a very simple conditional to only have it do it if those other cabs exist. If not, I can always just use jdeboeck's batch files . Regardless, your work is to be commended! You're providing a HUGE service to everybody on this forum, so many well-deserved kudos to you . And you should be fine with the assumption of everyone using 800x600. At least I hope nobody's installing XP on a system that can't do better than 640x480 .
