[OS X TeX] using Find function

[Bridget Kane]

Hi

I cannot seem to ‘Find’ in my tex files any more. I have the latest version of TexShop and I’m on Yosemite 10.10.2

Apologies if I’m asking about something that is well known and resolved, but I cannot see any reference to others having this issue.
I’m wondering what I may be doing wrong.
In TexShop preferences I have OgreKit Final Panel checked

Any  help or advice will be sincerely appreciated.

Bridget
