Upon re-reading the paragraph I wrote, I can see how the text might have been ambiguous. I was trying to express that there was a cost constraint on the part. Adding the cost of an EMBASSY or SEE environment to the purchase of every new PC is more than the market for bare-bones or even mid-range PC's will bear. --Lucky
