I discovered by accident that in Desktop Explorer it is possible to create an Autorun Scenario by dragging my log-in entry to the Scenarios entry. This is a very clever feature, and a wonderful thing to have when logging in as an alternate user.
Unfortunately, I keep come alternate desktops (virtual and non-virtual) in my log-in entry, but the scenario created ignores the enabled/disabled status of a desktop and just enables it. It would be nice to enable or disable individual desktops within a scenario.
