MSCRM shows this dialog box and keeps showing it no matter how long I wait for it. After an hour of research I have come to know that it’s a known issue with IE7 and MSCRM and Microsoft has provided a hot fix to resolve this problem. If you simply close this dialog box after some seconds then publish the customization, it works. Here are details of my findings and the Microsoft hot fix available for MSCRM 3.0.
