yes, try <a style='text-decoration: underline;' href="http://www.c-h-e-s-s.com" target="_blank">www.c-h-e-s-s.com</a> its the program in question, searches about 20,000
board positions. IE will timeout after 10 seconds so about every 3 seconds
it finishes the script then returns 1/10 second later on a timer, takes about
4 or 5 runs to make a move you can see the lightbulb flashing every time, that's
actually to get around the 10 second timeout.
Try selecting a menu option while its calculating.
IE will continue running if you select continue, but times out again at about 1 minute
and 10 minutes. IE must allocate some memory, the chess program is using
about 5 of these arrays.
But that's a processor intensive application playing chess, large arrays don't tax
the CPU generally. Its only about 100kb RAM, IE probably has 1MB or somewhere
around there allocated for javascript variables.
