In this case, your problem makes sense. Mathematica 2.2.1 had some inefficiencies in the way arrows were drawn; the resulting PlotField graphics often used up memory space allotted for rendering. You can fix this by obtaining from mathsource (ftp://mathsource.wri.com, http://www.wri.com/mathsource/): /Enhancements/Graphics/2D/0206-424/WinArrow.m If you're using the 2.2.2 professional version, then you should already have this fix. If this is the case, then you should send in examples of failed PlotFields along with your license number to support at wri.com, Wolfram's e-mail support address. They can determine what the problem might be. John Fultz Wolfram Research, Inc.
