I'm having a problem switching to local aliases and then modifying the alias list. TCC 11.00.37 Windows XP [Version 5.1.2600] TCC Build 37 Windows XP Build 2600 Service Pack 3 I normally have Option / Local Aliases unchecked and use global aliases. I clicked Start / Run / <path>TCC.EXE then typed: D:\>*option //localaliases=yes D:\>*alias z=foo As soon as I press Enter, the TCC application vanishes. This also happens when it is a tab within TCMD. My hope was that by using option localaliases I could do some alias testing without harming my global list. -- Jim Cook 2010 Sundays: 4/4, 6/6, 8/8, 10/10, 12/12 and 5/9, 9/5, 7/11, 11/7.
