I run an app called WinRoll on startup. You can roll windows with a right click on the titlebar (limiting the system menu to the program icon) Mine is resource hacked having its icon removed so that it doesn't appear in the system tray. I think you could *SystrayHide it but when I can I mutilate these service-type programs directly as I see fit. >:DDD

There are other options with this app but I don't use them. Something about right clicking on the titlebar buttons for other functions. I think one is a transparency toggle.

There's also a new version of Nuonsoft ShellEnhancer that also rolls up windows in addition to its slew of other features.

If you insist on using litestep it's sort of tricky to get previous window classnames. See http://www.litestep.net/index.php?section=4&action=view&catId=8&id=1413

EDIT: (WinRoll, not WinShade. ugh)
