That's the hard part:  there isn't one.  It's a large collection, and 
sometimes it works great for several thousand iterations, then other 
times I'll see garbage in a field without a crash, and sometimes garbage 
with a crash.  It crashes on different files, and after a different 
number of iterations each time. :\

I think the thing about images may get us closer to understanding this 
anomaly.  In my own tests any gabage that appears is always after the 
first image referenced in my htmlText.  I've been running a test in the 
background in which I'm not including in the image references, many tens 
of thousands of iterations without a crash.  Hmmm....

It may make a difference with the crash (and certainly with subsequent 
performance) to redesign the main routine to cache the files and 
reference the local cached copy for display.

I needed to add that anyway, so I'll do that now and report back on how 
it works out.

On the upside I know this can be done well because WebMerge has been a 
similar method for years, and with many copies out in weekly use (with 
some customers daily) it's never crashed yet.

Hopefully I'll have good news and a recipe or workaround to report by 
morning...
