Re: opacity "bleeds" in V7 graphics? [compared to V6]

Hello MathGroup:

In reply, I have received 2 approaches to this issue:

1. From WRI support: appears to be a Windows-only V7 issue, bug
acknowledged; use PlotPoints->50 as a workaround
2. From DPark: use MaxRecursion->4 instead

Both approaches remove the "bleeding".

Regards..
