When I use Timing Analyzer to analyze my design by running "Defining Endpoints" on the same TimeGroup multiple times, I find that the following error occurs on the second attempt:
FATAL_ERROR:GuiUtilities:Winapp.c.170
When will this be fixed?
This problem has been fixed in the latest 8.1i Service Pack available at:

The first service pack containing the fix is 8.1i Service Pack 1.
