Blurred windows having installed HD5450

[optimize]

I have just installed a Radeon HD5450 card in a Dell Optiplex 755. Brilliant graphicvs generally BUT some application windows are opening with a pin sharp frame but slightly blurred contents in some windows. Can anyone help? All browsers work fine..except Opera which has gone all fuzzy.

Make sure Morphlogical Antialiasing is turned off in the ATI Catalyst control panel

Thanks so much for your reply.

I cant see this particular function refered to in Catalyst - can you shed any more light for me?

Thanks
