ComputerWeekly: Microsoft has admitted "Some websites may not be displayed correctly or work correctly in Windows Internet Explorer 8 or in Windows Internet Explorer 9 Beta." In fact, more than 1,100 public sites like Youtube, the Wall Street Journal, UPS and others do not display correctly with IE9. However, the problem may be even worse with internal enterprise sites and Web applications.
In a recent survey, IT managers expressed concern about IE compatibility with intranets, SAP, Oracle apps, PeopleSoft, Salesforce, Business Objects, SharePoint, CRM and ERP systems and financial market data applications. And 52 percent of those surveyed said IE8 problems were inhibiting the rollout of new applications.
