Hi Jean-Marc,

Thanks for the reply.

Sure, the example I posted is not particularly large or complex (but 
it does demonstrate the problem). When calculating RegionPlot with a 
troublesome function that requires a very tight mesh, however, the 
problem is much worse. (Displaying the PDF in Acrobat Reader is 
visibly delayed as it stops to draw every single blue polygon.)

I can't test out a more complicated example until I get back to my 
office but you might find that this produces a more troublesome PDF:
   ContourPlot[Sin[x y],{x,=E2=88=925,5},{y,=E2=88=925,5}]

Hope this helps,
Will
