I'm using several standard text widgets in my right sidebar. I have titled one of these Iraq & Afghanistan. Everything works as expected.
However, I've been using the XHTML Verifier at w3.org, and it doesn't like by using an ampersand symbol in a title here. So, I replaced the & with & Fine. Everything still works as expected and the page now passes the XHTML validation test.
BUT, whenever I make any change to anything on the right sidebar (which I do constantly), the title reverts to Iraq & Afghanistan instead of Iraq & Afghanistan, and the page flunks validation again.
I'm a rookie & am learning by doing, so my apologies if this is an elementary question. Can anyone help?
