I keep the Information Window up while I am reading so that I can quickly lookup words or verses found in my reading. The information defaults to fulling the right side of the screen which is perfect. Unfortunately it only shows me a portion of the definition of the word I am hovering over.
Even more unfortunately, in the case of definitions it usually doesn't get to the definition before it cuts off. It tells me all of the preliminary information but right as it gets to the definition it is done. I must open the dictionary anyway 
I could understand this behavior if the definition/passage/whatever is too long for the Information Window but in the case where it is not too long why cut it off?
A picture is worth a thousand words so here goes...

Notice all of that unused whitespace and the lack of a meaningful definition.
PS: Yes I know what ability means this was just a good illustration of the problem
