Hi,
I understand that when you click on Edit this task in the message bar in InfoPath 2010, nothing happens. Does this happen when you open the email which contains the ‘Edit this task’ link?
If so, you can try to check whether this key is in your regedit. If so, you can delete this key and have a test.:HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{00000000-0000-0000-0000-000000000000}
Back up the regedit keys before making any changes. For more information about backup and restore the regedit, please refer to these sites:
