Powerplay 6.6 vs Internet Explorer 7

[FrederickL@hotmail.com]

Hi,

When I try to open a cube from cognos connect (with IE7) in Windows mode (to open the cube with powerplay 6.6 installed locally on my desktop), I receive an error message that tells me that my web browser does not have needed functionalities.

It's working with IE6 and Firefox 3.6.3; is there a solution / workaround to open a cube with ie7?
What is the "needed functionalities" IE7 doesn't have that IE6 have(!?)?  ???
