I believe our TSR shipped in 1988, and I think Solly's was about the same 
time, if not earlier. I'm certain we competed for the same prospect in 
Australia in 88-89, with similar functionality. It had absolutely been in 
our product for at least a year or two when I  moved to the States in 
January 91.

I always thought Hilgeave (sp?) was without merit, although their idea 
probably preceded Symantec into the market place.
