well, hmmm, more things are changing... xrdb actually does merge properly, both manually on the command line and automatically within xinitrc. i've verified this with "xrdb -query". however, even though the query shows a "xterm*saveLines:500" as the only entry, new xterms do not actually save lines. even if i quit and restart X. this is all with the default apple X11 SDK installed straight from the OS X 10.4 DVD that came with the computer. i've tried it on one computer with fink, and another without, and both don't work. i've tried deleting X11.app, /etc/X11, and /usr/X11 and re-installing, still no go. this is a default stock system, with only a ~/.Xresources file added that has a single line as above. how could it possibly not work for me and yet work for everyone else!? i've changed nothing concerning X11 except adding ~/.Xresources!!
