Hi,
I'm working nicely along, when all of a sudden Mathematica tells me that
essentially it can't NIntegrate[Cos[a], {a, -Pi, Pi}]. After 30 minutes
of searching, I discover that I have an invisible TextCell[""] attached
to the expression.
First of all, I don't know what I did to put it there. What DID I do?
Some inadvertent Ctrl-Key combination?
Second, TextCell[""] is mostly invisible and hard to find. Is there a
way to make it visible or to find it more easily?
Many thanks in advance,
Sam
