The Find function performs very poorly in long articles. I wanted to search [[Malaysian Airlines Flight 370]] for the misspelling "bouy". But the script began to search as soon as I typed "b", looking for all letter "b"s in the article. This leads to hangs/"long running script" errors in both Firefox and IE.

The "instant" find feature should perhaps be disabled in long articles, or it should only activate after a certain number of characters is typed.
