Strange behaviour with ie5.0 onclick

ie5.0 is very fussy about the onclick in a href

This will behave differently in ie5 and ie5.5 and 6:



in ie5.0 this will just invoke the href.
in ie5.5 and 6 this will invoke the onclick and invoke the href,
which gave some strange behaviour where the browser returns
immediately before the response comes back from the server

The fix for this is to include a return false;



so in all cases only the onclick is invoked
