我围绕 Unity 构建了一个简单的应用程序框架。即表单和用户控件被描述为 xml 并动态构建。我有一个包含 ComboBox 的表单，当它关闭时会导致下面详述的错误。如果 ComboBox 替换为 ListBox 控件，则不会发生此问题。

一些谷歌搜索引发了一些关于我无法安装的补丁的报告.. KB923028

当我的 .NET 应用程序正在运行时，尝试将系统显示切换到“超大字体”时，只需在 Windows XP 上点击它即可。

似乎这与格式错误的字体或类似字体有关。

当控件使用 XP/Vista 样式然后在旧版本的 Windows 上运行时，我已经看到了这种情况。

我在系统上安装新字体时看到了这个错误。您是否安装了新字体，或者最近安装了新字体的程序？

其他 .net 程序是否正常运行？如果没有，最好的办法可能是重新安装 .NET 框架。
