请用过wxpython中scrollpanel的同仁指点一下,scrollpanel滚动条导致RadioBox错位

lcfeng

以下代码运行时如果窗口最大化最小化之前左边的scrollpanel的滚动条如果已经拉下了一定距离
RadioBox就会错位，但如果不是RadioBox,原位换成TextCtrl又完全正常，各位指点一下，先谢谢了

环境：
ActivePython-2.5.4.3-win32-x86
wxPython2.8-win32-unicode-2.8.9.1-py25

只能变通一下解决问题了
没有得到指点，最后只好结合StaticBox,StaticBoxSizer和RadioButton达到同样的效果
