8.1i Timing Constraints Editor - UCF file cannot be saved on a network drive


The Timing Constraint Editor cannot save or overwrite a user constraint file (*.ucf) on a network drive.


To work around this issue, manually copy the constraints created by the timing editor in the UCF file.

This issue is fixed in ISE 8.1i.
