It's very annoying to have to distribute stackable items like bullets or charges, since I have to hold down the little +/- buttons to get to where I need. I've heard you're supposed to be able to just type the number in, but that hasn't worked for me; it seems to just run the hotkeys instead, even if I clear them. Is there any way to run the dialog without holding down the mouse button?
Tried typing the numbers using the numerical keys on the left hand of the keyboard? It doesn't work if you're using the ones above the letter keys.
