When I re-target a new device in my ISE project and run the "Configure Target Device", Project Navigator crashes. I see the following error:
This occurs when I have run implementation and created an iMPACT project file (.ipf). After I rerun implementation and select the "Configure Target Device" process, the Project Navigator GUI crashes.
The work around is to delete the created .ipf file in the project directory after re-targeting a new device. A new .ipf file will then be created. This issue will be resolved in ISE 11.1.
