Installing Ghostscript 8.11 and GSview 4.5 under Windows XP Pro SP1 on a new 
Sony Vaio V505DC2P laptop, I noticed that anti-aliasing display settings in 
GSview 4.5 (1, 2, or 4 bits) have no effect whatsoever (i.e., the screen 
output always corresponds to that of the 1-bit setting). Replacing GS 8.11 by 
7.04 cures the problem. I include a brief postscript test file that shows the 
problem. On the Sony notebook, the problem is always reproducible, i.e., GS 
8.11: bad; GS 7.04: good. I haven't done any tests with other versions of 
Ghostscript.

Note, however, that of the four PCs I have, the problem is specific to the 
Sony notebook; it does not occur on any of the other three (one of them is 
also Sony notebook -- an older Vaio Z505HS model).

Regards,
--Helmut Haberzettl

PS: I don't have clue which component is responsible for this behavior. The 
choice "MS Windows Display Driver" is just a wild guess.
