OpenGL输出窗口立即收缩到0 x 0窗口

我在OpenGL程序中遇到了问题，使用在Visual Studio 2012中编译和运行的OpenGLUT。程序编译得很好，当我按下运行一个800 x 600的窗口打开并显示我想要的图像。 但是，窗口会立即开始收缩，直到它在大约2秒内达到0 x 0，然后保持打开状态。 我不太确定问题是什么，Googlesearch没有提供相关信息。 以下是问题的一些截图：

上面的截图是在程序启动后立即进行的。 下面的屏幕截图是在程序启动后一秒钟左右没有任何交互的情况下拍摄的。

• 找不到System.Windows.Point
• IsIconic（）总是返回false，而OpenIcon（）永远不会打开窗口
• gtkmm 3个窗口64位
• 无法findWindows Azure运行时2.5
• 如何通过块上传背景块中的文件？

输出窗口继续收缩，直到尺寸为0 x 0。 这是我的代码，任何build议都会有帮助。
