Dear All, I am not able to delete a zone in TRNBUILD. The feature is not enabled in the version I have (TRNBuild 1.0.92) : ZONES--> "Delete Active Zones Ctr+F2" I can modify the *.bui file after opening it with a text reader but sometimes I get an error message and then the program crashes. Can someone help me with this? Thank you in advance Best regards Eleni Ampatzi
