From: blstuart(a)bellsouth.net I've done a little digging in my spotty library. (It's so nice to finally have enough shelves for all the books.) And I've come across a few additional references thay may be of some help. The first references come from a set of inter-office memoranda from Xerox dated in 1978 and included phrases such as "window-based display," "window- oriented display," "windows with standard behavior" and "non-preemptive window behavior." These memoranda are discussions about a programming environment and mention that both Smalltalk and Mesa already had window-based environemnts at the time. The next reference comes from Interface Age magazine, July 1981. In the article "The Video Display Revolution," Table 2 lists features of various terminals. One feature listed for the HDS Concept 100 terminal is Windowing. The last reference I came across prior to 1983 is in the August 1980 issue of Byte. In an ad for Software Development and Training, Inc., a text editor is described as having "FULL SCREEN window displays..." Not all of the references described windows as we currently think of them, but they do illustrate that the term was in general us in the field of computer user interfaces well before Microsoft trademarked it.
