Does anyone know of any workarounds for these bugs When I build a form with no border and transparency key (to make a non-rectangular custom-skinned form with a Region), I get no context menu in the taskbar (right-click -> move/resize/minimize/maximize/restore/close), and when I maximize the form it doesn't respect the taskbar boundary and will go full-screen.

GDI+ borderless/transparent form bugs... No context menu in taskbar. Maximizes on top of taskbar.
