Toolbar controls such as the font name and size pickers respond to setting the Appearance.Rounding value, but not the TTMSFNCToolBarButton - it's corners don't change.
Also, the rounded corners on the controls that do work look pretty bad - is it possible to get anti-aliased borders?
Hi Pieter - I realise now what's different - I was using flatstyle = true on the button and = false on the font control. So is rounding not possible with flat style?
