Hey Nicholas, looking over that list, do you know where one can find updated graphics.library 40.25? I recently noticed a *17 page long thread* on it over on EAB, but nowhere in all that mucking about did anyone say where to obtain it. 
I've got a fresh install of 3.9 on one of my systems along with BB1, 2, 3, and 4, and SysInfo reports I'm still on graphics.library 40.24.
Just curious! 
mfilos and Gulliver are probably the best guys to ask about that. Hopefully they'll spot this thread and post here.
IIRC there were problems with the new graphics library but I'm not sure what as it's a while since i kept an eye on it.
Still part way through rebuilding my A3K so when I've got her put back together and reinstalled I'll probably look at finding the new graphics.library, dos.library and scsi.device etc from the threads i've got bookmarked from EAB.
