What is wrong with this Script logic?

[J. Landman Gay]

It isn't really hung, you can command-period to abort the infinite loop. 
But still. Hm.

It locks up for me too, and it didn't used to. Not only that, but if I 
abort the script I still get a final dialog, and if I hit Cancel in that 
one, I get the same odd results you do -- part of the script goes into 
the ask field, which then displays "ask warning". How weird.

The reason you aren't getting a recursion error is because it isn't 
really recursion (the handler doesn't call itself.) It's just a loop. 
Only the ask dialog should be modal and stop the loop until you dismiss 
it, then evaluate the entry and loop again or exit. That's not 
happening. It looks like the script keeps running even with the dialog 
up, the loop backs up with multiple calls to the ask dialog, and 
everything hangs.

Something's wrong. I think it's the dialog.
