Why is my quick reply box so big and how can I make it smaller?

[BudgetHedgehog]

It's a quick reply. It shouldn't take me longer to scroll to the bottom than it did for me to write the reply. How can I make it like, 1/4 the length? I know there's an option to resize it in the bottom left, but clicking and dragging does nothing, and double clicking it puts a cursor right at the top.

See the little triangle at the bottom right? Click and hold it, then move your mouse up to make the quick reply box smaller - at one point you must've made it bigger too, because this is not the standard size

Nope, doesn't work. As I said, it just puts a cursor right at the top of the box.
