CRM3 problem with Import Customization in Internet Explorer 7.0

I’ve not been able to load customisation into the new self-contained virtual CRM3 environment, all the latest patches were applied and the CRM Rollup.

When importing cusomisations the MSCRM shows this dialog box and keeps showing it no matter how long you wait for it.

After nearly losing my sanity after a day of no joy I’ve finally found this article, it’s caused by using a combination of CRM3 and IE7 .

You can log a call to get the hot fix if you really need to use IE7 with CRM3. In my virtual Windows 2003 environment I un-installed IE7 which resolved the issue.
