Hello, I am now testing and debugging the Grade 2 routines for BRLTTY. Last night they were working to some extent. However, I've run the new version so many times that now my Redhat 7.1 Linux seems to think that the new version is the one I always want to run. However, I want to go back to the old stable version for general work. How do I tell Linux to forget recent history? The new version is also now giving a "'core" dump when it is run with a translation table, which It wasn't doing before a change which could hardly be related to a "segmentation fault". Where do I find this core doump? Thanks. John -- Computers to Help People, Inc. http://www.chpi.org 825 East Johnson; Madison, WI 53703
