I'm working on an architectural visualization with 3ds Max 2011 x64 (DirectX 9, Windows 7) and JDownloader is downloading a couple of free hdri maps.
I'm experiencing an odd bug: if JDownloader is minimized to a button on the taskbar, right-click menus don't work in Max: they flicker and then disappear. If the taskbar button is hidden, so that it only shows as an icon in the notification area, menus work fine.
Best regards.
