Plan View panel seems to freeze with Internet Explorer version 7

When using Internet Explorer version 7, some actions performed in sequence might cause the Plan View browser window to freeze and stay frozen for about 5 minutes. After this timeframe the browser window resumes.

Cause and solution:

Action sequences that might cause this problem typically include opening multiple Plan View panels at the same time and refreshing the Plan View panels that were already open.

To avoid or limit this behavior add the Dynamic Workload Console website to the Local intranet security zone of Internet Explorer 7, with its default security level.
