<DIV><FONT face=Arial size=2>Is there a way I could have single stepped into
this to investigate myself? My speculation is that the graph of object
references is very large, or circular (and this is unhandled?). But
that's just guesswork.</FONT></DIV></BLOCKQUOTE>
<DIV dir=ltr><FONT face=Arial size=2>And I now see that having interrupted it
with the 'break' key sequence, I sensibly get a debugger. I'm not fluent
enough to read exactly what's going on, but by getting 'fullstack' in the
debugger, increasing the size of the top pane, and standing well back, I see
that there's a repetitive pattern on the stack. My guess - it's getting
caught cycling round a loop in the object graph. If it was just that the
graph was large, I'd expect the stack to be deep, but not so obviously
repetitive. Anyway - just a guess.</FONT></DIV>
