Code hints, where are they?

I seem to have a problem with code hints in Flash 8.

I have started to move to strict data typing but don’t get code hints!

For instance when I type the dot on the last line of this as explained in topic http://www.kirupa.com/forum/showthread.php?t=43761:

var myXML:XML= new XML();
myXML.

I expect a list of properties to come up for my XML object, but they don’t. I have checked my preferences panel and I have code hints enabled.

Am I right in thinking I should be getting code hints or not?
