I run WIN 7 on my PC, and there's an option to change the display from 100% to 125% to 150% to make the text easier to read. When I change it to higher than 100%, I lose some space like what you're running into. Maybe look at changing you display settings if you can, there's another checkbox after the one getting cut off in your screen shot.
You can also change the texts of scripts. Just open it in a text editor and search for the string you want to change, for example "Change all keys relatively".
It's hard coming up with texts that are both short and descriptive...
