Direct3D的DriverInternalErrorException异常

Question

我现在需要在一个form上使用direct3d画一些东西。
在form.show()之后，执行了以下代码PresentParameters presentParams = new PresentParameters();presentParams.Windowed = true;
presentParams.SwapEffect = SwapEffect.Discard;device = new Device(0, DeviceType.Hardware, form, CreateFlags.SoftwareVertexProcessing, presentParams);
现在的问题就是，如果我单独执行这个form，没有任何问题。
但是如果我把这个form作为一个MDI子窗体来显示的话，那么当我把这个子窗体最大化，然后再把父窗体最小化之后，
即使我画面上没有做任何的绘图，都会抛出这个异常。
异常是从Application.Run(new MainForm())中跑出来的。请问这个如何解决？
谢谢。

自己找到一个解决方案，把子窗口的MinimumSize设定为100,100就可以避免这个问题了。
