WhenI re-open a project that is already open, the Design Summary window does not re-appear.
NOTE: The Preferences -> ISE General -> Open Design Summary/Reports when project is opened is checked.
1)Open any project, theDesign Summary window is opened automatically if the preference is selected.
2) Without closing the project, re-open the project by selecting: File -> Recent Projects -> 1 - <path>/<project name>.
The project re-opens, but the Design Summary is now gone.
This appears to be an issue with Windows only.
The Design Summary can be opened by clicking on the Design Summary icon, or by selecting Project -> Design Summary Report.
To avoid this problem, close the open project first before opening it again.
