问题: 在Windows XP(SP3)下, Google Chrome浏览器可能无法正常显示Checkbox或RadioButton的图标, 仅显示文字部分.
解决方法: 打开Windows的任务管理器(快捷键: Ctrl+Shift+Esc), 在Chrome浏览器中切换Tab页, Checkbox和RadioButton就可以正常显示了.

参考: When you encounter the bug bring up the Windows Task Manager (taskmgr.exe) and browse to any page in another tab. Then go back to the offending tab and you should have your checkboxes back. [http://goo.gl/XAzV]
