BUGS ============================== Yes, there are some. Imagine. :( o In graphics, sprites will sometimes disappear. This happens in the old software engineering demo after excessive shooting, but cannot be reproduced consistently. Needs further investigation. o Nick has encountered a problem on his laptop, where there is an exception during startup: An unhandled exception of type 'Microsoft.DirectX.Direct3D.InvalidCallException' occurred in microsoft.directx.direct3d.dll Additional information: Error in the application. It is in the Runner.Direct3DSettings.InitializeFor(Control) method on initialization. Could be that he installed the wrong version of DirectX. Needs further investigation.
