First off, in Common Settings > untick Add AutoPlay handler
Personally I hate the autoplay feature in windows so I disabled it on all my ODDs. This also prevents the inadvertant installation of nasty stuff like Sony's rootkill as well as the not so nasty, but nevertheless annoying stuff.
There are a number of ways to do this. My OS is XP Pro and my favorite method is to use TweakUI.exe, one of the MS PowerToys. I believe there is a version of tweak for Vista as well.
Ahh, I see I'm typing at my usual "turtle speed" and was second place, yet again...:sad:
