 Judith Hann.  I don't remember Philippa Forrester being on it but I do
 remember Maggie Philbin. 
Hmm, I remember Judith, Maggie and Howard. I think the show had seriously gone
downhill by the Phillipa days (early 90s?) - less about the science and
technology behind the features, and more about dazzling people with glitzy
effects (same thing that happened to Horizon and all the others).
  Perhaps the flashing-square software was in the
earlier era of Raymond
 Baxter and James Burke (which I also remember). 
Sounds like that might have been a bit too early, though. I think Raymond
Baxter left in the mid-late 70s, and there likely wouldn't have been enough
home machines around then to justify the flashing-square feature. I'd guess at
it being early-80s.
