Something annoying about changing masteries

Ok, so I often change my masteries around and sometimes I use a guide to get an idea of what works for other people.

Now this is a relatively minor, but extremely annoying inconvenience, but Rito, is there some way you can make it optional that my league client window doesn't lock whenever I open my masteries? Sometimes I move the client outside of my visible desktop and I actually can't X out of my Mastery page because the mastery page locked the window and I covered up the X lol. It's actually really frustrating because the only way to fix it is to restart the whole thing.

Rito plz

TL;DR Make it so the mastery page stops locking the league client window, it's annoying.

P.S. If there's another place on the forums to post this, please let me know.;D
