Every time you’ve ever tried to edit a document in MS Word while a window (such as the font formatting window) is open you get nowhere. That window just sits there, open and waiting. You certainly aren’t going to make any changes to the document until you’ve made your choices and either clicked OK or Cancel.
Hard to believe that the Find window behaves differently?
Yeah, I thought so too, but then I tried it and sure enough it worked.
I had the Find window open, clicked out into the document and poof—my cursor appeared in the document allowing me to edit.
Now, I should mention that the Find window remains on top until you close it, but it does lose focus (its title bar lightens denoting that it isn’t the window with the current focus) and can be dragged around the screen.
When you need the Find function again simply click into the window, it assumes control and you’re back on your way.
