I have been submitting Fritz 7 to an ordeal of tests in my computer since the first upgrade to 0.2 engine version; and I have done, undone and redone many times the ieupgrade on GUI7a and GUI7b files, blah blah blah then with the more recent s.pack etc etc etc and... among the many zipped reserve files I have, I found a Fritz 7.eng file whose creation date is Monday January 1 2002, 11:38:29 and the file size 434,176 as the others. It just happened that I did find this version of the engine here. Shall we take it as a third file? Karen
