Hey Steven -
I tried what you suggested and it didn't work for me.
Don't know why the main Find box won't work properly, but I have just been using the Ctrl+T Title Pop-Up screen and it has been working for me.
On a side note, if I shutdown the program and restart it, I can type 1 letter, yes only one, and the menu appears. If I type another letter, the drop down menu disappears again and will not populate until I shutdown the program again. Even if I delete the text entered and retry, it won't work again.
