To Matt,...I now have Intel Core2Duo 3Ghz and 4GB DDR2...wow, fast. I upgraded to the Beta, unchecked the Tooltips and that stopped the Windows 2000 from crashing. Thanks again for your help.
To Anyone,...Could some kind soul with some spare time[gulp] do a tut or at least explain what the Painter shader is, what it does and how to apply it. [the bare bones river example not withstanding]. I'm sure someone else is as confused as I am.[?]
