OK, here goes - I am posting this as I am making the screen shots.
I currently have 4 tabs open, the first being my job page at GA Tech, the second being a Google Search for Nail Salons, the third being a page where I can download Nail Salon POS-type software for a trial, and the 4th being this one.
I go to the first page and try a search, and every thing works as it should.

I go to the second tab and try to find the word
business and search indicates that it is unable to find, including an audible response.

I click the highlight button and the word business is highlighted on the page, meaning it can obviously be found on the page.

EDIT: Added the following
However, this behavior does not occur on a new profile with only TMP installed, so it is not TMP specific.
