I am using the latest version (6.6) with Firefox 3.5.7, IE 7, and IE 8.  When I select the insert hyperlink icon and then the browse button next to the URL text box, I am unable to see .asp pages when browsing.  Is this a limitation of the tool or something I need to configure?

 

I attempted to test this using your example but you don't seem to have any .asp pages (or due to the issue I just can't see them).

 

Thanks
