Yes, this is a well-known bug present in all versions of ArtWorks 2. 
Fortunately, it is completely harmless, so fixing it has never been a 
priority.

Yes, this is a known bug, too. It must be some change in Adjust that I 
have not yet been able to pinpoint. This problem will have to be 
fixed, but only because it causes other problems.

I cannot see anything wrong. Transparency works fine here in a 16 
colour mode. The question is what you expect with only 16 colours 
available - actually, only 8 non-grey colours. These colours do not 
even span the colour cube so it is not possible to produce anything 
like an accurate match even with extensive dithering. When you export 
in 16 colours, a more accurate colour mapping algorithm is used.

Sorry, but are these 16 colour issues not really academic? Of all 
applications why would you want to use ArtWorks in a 16 colour mode? 
Even having only 256 colours really stretches things quite a bit, in 
particular when using transparency, but ArtWorks does its best, but 
there is little use for ArtWorks in a 16 colour mode.
