AAD versions 0.29, 0.28.3, 0.27 and 0.24 hang when starting up after installation. I'm running Vista SP1 and .net Framework 3.5SP1.
AAD takes several seconds to start and a window border is drawn without any inner content (the inner area is transparent when the window is being moved), the CPU usage goes up to 25% (on an AMD Phenom 4 core) and ram usage is increasing. No error message appears. however, when uninstalling 0.29 and installing any of the older versions, a second smaller window border appears which seems to be an update check, but it also has a transparent inner window and is unusuable.
I've uninstalled AAD and .net completely and reinstalled .net, then AAD 0.29. Now the inner window is white and when moving the mouse inside the window, the cursor changes to a text cursor in some areas, but the window itself is non-reactive. Memory usage is at about 20MB but after a minute or so the CPU usage is up at 22-25% again.
