Ie filter:alpha(opacity) black border

问题:

Having an issue where filter: alpha(opacity) is adding black jaggys around the edge of my images.

Interestingly not around the image itself but around the edges of its transparency (it is a transparent PNG).

But this is also happening on text I have absolutly positioned.

Any help would be very appretiated!

It looks fine in other browsers, obviously not using filter:

Thanks.

For anyone who ever finds this.

Result I eventually found on MSDN is it's possible using MS propreity CSS, but its completely impractical.
