The restore worked but the backspace keys on both the 8500 and
780 still do not function.

I don't remember going for this long without a backspace key and I'm
wondering how far back we'll have to go? Perhaps just another month?
but I'm wondering about the 8500 now because that means it too would
have to go back that far.

I thought of another possibility since the new mouse corrected the problem
I was having with things opening etc. Maybe the problem however unlikely
is that the keys themselves are bad on both keyboards? I think I may have
some older working ergonomic keyboards left that I could try using one of
them to test it.

Thoughts/suggestions?
