Xcode find in document stuck in case-sensitive

When in Xcode editing code for my o开发者_StackOverflow社区bjective C files, I often press Command-F to bring up the little Find-In-Document banner across the top. Sometimes this gets stuck in case-sensitive search, and when it does that it also won't loop through the entire document and sometimes won't even display the selected found string.

I can't find any options to turn off the case sensitivity, and I never intentionally turned it on. I've restarted xcode several times hoping that would be it but it's changed nothing.

Slightly off-topic, but this was the best place I could think of to ask this question. Thanks for any response!

EDIT: I've also tried restarting the computer. Still no dice. Also this happens on any project I open in xcode and is not specific to one project.

Anna's comment is the correct answer: When you press Cmd-F, clicking on the little magnifying glass next to the search input brings up a menu where you can check/uncheck Ignore Case.

You can set parameters for search by clicking on magnifier placed in left-side of search-bar. There is provision to select/de-select "Match Case" i.e. case-sensitive search on pop-up shown. Below is screenshot for the same.
