After launching Timing Analyzer, I select a constraint header hyperlink, right-click "Edit Constraints" and obtain one of the following:
+ Constraints Editor launches, but the incorrect dialog appears
+ Constraints Editor launches, but no dialog appears
+ Constraints Editor launches, but the dialog appears for a different constraint
+ Constraints Editor launches, but the dialog is populated with incorrect data
+ Constraints Editor does not launch
+ Crashes Project Navigator
To work around this issue, manually edit the UCF.
This issue will be resolved in the next major release of the design tools.
