When I first previewed code nothing happened- hence above comments. Just before posting I previewed again, and wala. Wish I could remember the quote that goes something like "stranger things than are dreamt of in your philosophy"
EDIT: \displaystyle did it. Which raises the question, should I add it or let MMF do it?
EDIT: Good Grief! Now what happened. All I did was add edit to original post without changing anything and I get dollar signs added to my code. Is this telling me I have to pay? Can't wait to see what happens when I submit this edit.
EDIT: Posted last edit and worked again.
EDIT: Refresh!!! Refresh!!! Just as Hoempa said above. It's not the time after all.
To quote from a movie:
Pain make man think
Thought make man wise
Wisdom make life endurable,
which is wrong on every count, but cute. Take-off from Ecclesiastes.
EDIT: But that means you can't rely on "preview."
"In much wisdom is much grief, And he who increases knowledge increases sorrow." Ecclesiastes
