Extjs3.x 在IE10中弹出窗口后有阴影如何解决？

我也遇到这样的问题了，我智能跟客户说不要用ie10~~~

哎 难道没别的办法了吗

window最后显示的时候调用syncSize方法

/*********************************为阴影 添加IE10兼容*************************************/

漏贴一部分代码
    /***************************************添加IE10标识*********************************************/
    Ext.isIE10 = /msie 10/.test(navigator.userAgent.toLowerCase());
    Ext.isIE6 = Ext.isIE6 & !Ext.isIE10;

添加这句试试       shadow: false,

menu中添加这句可以
