Changing the parameter dialogue box ?

[GaWill]

Hi im currently using reports which ask for users to enter parameters. I was wondering if it is possible to change the crystal Enter Parameter Values box that is displayed as it doesnt look very user freindly.

If anybody knows how to change this box it would be a great help.

Many thanks
