Re: IE7 hangs on LivePages

Hi glyph

Went back to nevow.0.9.0, fired up the examples and yes, you can reload 
the calculator with IE7 as often as you like. The 'last gasp' message 
sent synchronously seems to introduce this particular choking phenomenon 
and was most probably introduced with changeset 13798.

Too bad I'm not too familiar with the inner workings of athena. Can you 
give me a hint where in this massive changeset you would start looking 
for a solution?

Would it be possible to have that 'last message' thing as an option?

Thxs, Werner
