I must've screwed up my test of a couple of months ago, or misremembered
what I did. Anyway, I just checked it out again and it works! If you
extended-select a disk or a drawer along with the tool, the tool does
indeed get launched in that directory. One possibility for my screwup is
that CLIs (or commands passed to AmigaDOS) seem to come up in SYS:. I
spotted that one with Memacs which, in fact, would have fooled me if the
situation hadn't been so weird. I had selected DOCS1: (the DF1: volume)
and launched Memacs (in Extras1.3:Tools/), but when I had Memacs pass the
"dir" (which was resident) to the system it would prompt for and list the
SYS: volume (WP:). However it would load files in from DOCS1:.
