I'm using transparent labels on a formex in order to tie the label's colour in with whatever windows theme is in use but unfortunately the labels are just a little too transparent and take the MDI forms beneath the new form as the label background instead of the form itself.
A FormEx handles its background differently to a standard Basic4ppc Form as it doesn't have a Forelayer and backlayer. A transparent label won't draw properly on a FormEx as when it is transparent it tries to draw its background from the Form background bitmap which contains the Forms forelayer and backlayer - which don't exist on a FormEx.
