The thing works both in IE 6.0 and FireFox 1.4. but with some problems.
IE crashes when one refreshes the page or leave the page. This happens
only after calling the Java method more than once. It does not crash if
the Java method is called just once and then the page is refreshed.

FireFox does not crash at all and no error whatsoever. However, it
takes a good minute or two to display the newly created element. And,
if during that time  if one calls the Java method, it gives an error
and it never works afterwords. But, once the Java method returns after
the first time, it works robustly no matter how many times the Java
method is called or if the page is refreshed or closed.

Can any LiveConnect guru please take a look at this code and let me
know whats wrong with it.

Thank you very much in advance.
