We're using a RadDock and as we have to display some localized labels in there, we don't want to give it a fixed size, but we want it to behave in a 'shrink-to-fit' way. For some reason the width property is initialized with a DefaultAttribute of 300. When we set it to Unit.Empty it looks fine in Firefox (it shrinks to fit as expected). Unfortunately in IE7 the Rad is doing strange things, its right border always expands till to the right window border. Do you have any idea why it is doing this?
