I agree -- I sent RSI some updates for Apple's X11 -- anyone with v. 0.2
should update immediately to 0.2.1 (if for no other reason than to recover
the default quartz-wm instead of tvm, which was slow and crashy). It is
fast -- I am so happy to finally be able to run envi and idl natively,
instead of in classic (and I can return that stupid USB dongle at long
last!)
Have you (Karl) or anyone else managed to access Aqua fonts yet via IDL? I
was under the impression Apple was going to try to link the available Aqua
fonts to X11, although this might be a pipe dream. It'll also be nice to
see if they can modify the default color scheme of X11 to match Aqua...
