Did you compile with support for dynamic loading of drivers? This can  
happen when libtool is used to compile and link (as with PLplot)  
dynamic modules, since it doesn't do the Right Thing on OS X (at  
least it didn't last time I checked, quite some time ago).

You could try
1) upgrading to the latest libtool or
2) disable dynamic loading of drivers (can't remeber the exact  
incantation, see ./configure --help).

I checked, and for some reason,
         setenv PGPLOT_BACKGROUND white
         setenv PGPLOT_BACKGROUND black
doesn't affect AQT (it should have)

You should be able to explicitly swap color[0] (background, default  
black) and color[1] (default white) in your plotting code, after  
initializing a new page. That should give you black-on-white for AQT.

I'll have a look at it, but again, no promises on dates...

Not exactly large bundles, but I'm not complaining. I've got a very  
satisfying job doing multimedia research for Ericsson.
