I've recently updated my Mac Mini to OS X 10.8 (Mountain Lion). When I open ADE, the window is blank until I either drag the window off-screen and back, or it is obscured by another window, then visible again.
ADE was already installed when I did the Mountain Lion upgrade. My current version is 22.214.171.1241.
Does anyone know how I can solve this, or if it's a known bug?
