OK, I can't figure out how I did this, or how to undo it. Probably something simple, I'm just not seeing.
This is on the BI console, not the web ui. Oops edit to add version 6.0.1.13
Put your mouse over the clips list (you may have to click on 1 of the items) then press and hold down the <CTRL> key and scroll the mouse wheel up or down to get it back to the size you want!
