Search funtion problem using upper/lowercase on an iMac

[FuzzyUK]

When searching with iMac using Command F, it demands upper and lower case characters to be entered. This is annoying as all smallcase entries would miss a word, like a name for instance, that starts with a capital letter. Is there a way round this?

Very odd, it doesn't do that for me, I just tried.
