Sorry I'm jumping in so late here, but if anyone's still listening...
">WinPatrol</a> is an excellent task manager utility that, among its numerous useful functions, lets you choose the delay intervals for startup applications.
I now prefer <a href="http://www.anvir.com
">AnVir Task Manager</a>, with similar functionality. However, AnVir's main drawback, in my opinion, is that the startup delay is not configurable -- it's 1 minute for all startup apps you choose to delay.
Both come in free and paid versions. I briefly reviewed WinPatrol in post <a href="http://jonathanstool...l-your-startups.html
">#11</a> of my utilites blog, and AnVir in post <a href="http://jonathanstool...love-in-my-life.html
I hope this is helpful.
