Transparent Label... Bug????
I've posted a code example below.
A form with a LinearGradientBrush so that backgrounds a nice shade...
Then simply put a Lable on the form with with its background color set to transparent.
But it seems to cause an exception any one no why? or can any one think of a work around?
Cheers
