Happens all the time. I'm surfin', surfin' ... then I want to go back to a previous page. I hit the back-arrow, and bingo-bango-bongo, up pops a webpage I visited back in February, and I can't backtrack to the page I was on 25 seconds ago! Believe me, I've looked at the tabbing section of the online 'Pad manual and Googled this phenomenon, but I can't predict when it'll happen or why.
I know no one in Cupertino can be assumed responsible for this boneheaded bug (oops - I said a ba-a-d word!), so what am I doing wrong?
