I dunno, Chuckslut, (heh)...according to applemuseum.bott.org, the Lisa indeed did have preemptive multitasking..

"...The Lisa team had added extra features not included in the Alto including the dragging, double-clicking of icons, pull-down menus, a menubar at the top, and the famous trash can. The Lisa OS also had preemptive multitasking. This and the fact that the Lisa team had no guide or set of instructions to follow, therefore having to "reinvent the wheel" according to what some of them had seen is reason enough to give them the full credit they deserve. See a Lisa OS 7/7 screen shot, or a color picture of the Lisa."
