According to IMV (beta draft), which I don't have in front of me, but I have a pretty good recollection of the ShutDown Manager (after using it to write my ShutDownSound INIT), the ShutDown command in the Finder works as follows: It calls the ShutDown Manager with trap _ShutDown with a selector of 2, ShutDwnPower. The ShutDown Manager then goes about its business of shuttin down the Macintosh by first closing all open apps (if you are running under MF), then closing all open Drivers (such as DA's/Printer/Disk, etc.), then it goes through all mounted drives and UnMounts them and then finally either turns itself off (if you are a Mac ][) or puts up that funky dialog. (If there is a ShutDownProc installed, like my SDSound, it will be executed as part of this procedure as well). All this is described in IMV in the chapter on the ShutDown Manager, or in my article in the September Issue of the Champaign-Urbana Macintosh Users Group Newsletter. +--------------------------------------------------------------------------+ + | + + Leonard Rosenthol | USnail: 205 E.
