For some reason this code has recently stopped working. Also it never worked on find and replace, not sure why...
edit - Might be something to do with the formatting of the brackets. I can type new brackets and use find and replace to change them but not the ones that are currently there, but they look exactly the same... this is really weird. Not sure how your code worked before but doesn't now.

It's like it infects the bracket next to it. If I delete one half of the bracket, save, and try to find it doesn't work. If then I do the same to the other half, it still can't find it. Repeat as many times as you like. If I delete both and replace with my own brackets it works.... any ideas whats happening to me?
