Is that physical memory or virtual? On OS X I've seen seemingly small 
apps take up a surprising amount of virtual memory, but operate in a 
much smaller physical space.

Although FWIW I've not seen my Rev usage climb that high while running 
these tests.  Are there plugins or other stacks running which may play a 
role here?

I did the test both in Rev with only the default installaton, and in 
MetaCard loaded up with several megs of my own tools.  Same good result 
with each.

In theory it should make no difference, since the Inspector is setting 
the same property I set in script.  If anything, one might expect the 
script to do a better job of exposing any issue with that since it's 
working harder, setting the color over and over with each iteration.

Unfortunately this week I'm up to my gills in client work, so I won't be 
able to run another test on this.  It may be helpful to submit a test 
stack which reproduces the problem reliably on your system to 
support at runrev.com, so they can reproduce it there.  With their 
low-level debugging tools I'm sure that if they can reproduce it they'll 
be able to fix it in short order.
