Latest Button changes break dialog in IE6

本文介绍了一个在Internet Explorer 6浏览器中使用ExtJS库时遇到的问题：当尝试销毁包含按钮的对话框时，会出现未知的运行时错误。通过提供一个简单的示例代码片段来重现该问题。

Here is a simple snippet to show what is happening.
If the button line is removed and dialog.destroy(true) is called after show....everything works fine.
when destroy is called if the button is there it now chokes in IE6...
Unknown runtime error Line:21 Char: 15848
The prior release did not have these problems...
