In my XP SP3 it the DPark's solution works perfect. Beside, I tried several PlotPoints settings and see that below 150 points the hatching starts to go uneven. With 100 points it becomes pretty unusable. And, I have had similar problems with *RegionFunction* when applied to some rotated and translated functions plots. The corresponding (rotated/translated) *RegionFunction* specification sometimes works and sometimes does not when applied to the same (rotated/translated) functions. I solved the problem by applying the corresponding 'rotation/translation' to the original 'PlotRangle rectangle' and then plotting by hand only the points of the shifted functions lying within the rotated/translated PlotRangle rectangle. My problem seems to be related with the computation of the intersections with of the converted functions with the corresponding new *PlotRange* limits. The examples I have are too large, and perhaps tricky, to be posted here. I will try to isolate some simpler example to post it. E.
