对于由于安装IE9RC引起的sidebar.exe及svchost.exe的严重内存泄漏问题，Internet Explorer Developer Center的一名MVP已做出回应，指出内存泄漏是由于桌面小工具与IE9RC不兼容导致的。但不知为何此MVP说BETA而不是RC。请有相同症状的朋友自行测试此解决方案是否有效。原文如下：
"the sidebar.exe and one svchost.exe got memory leak" - one of your sidebar widgets has a memory leak... disable them one by one to find the culpret or check with the vendors for updates that are compatible with IE9 beta at least.
