Any way to control the size of the message box?

Evening/morning all. My subject pretty well asks the question: is there any way to control the size of the message box? The last few times I’ve built modules, I wind up with a message box area that takes up half of my screen every time I load the mod or start a new game. I have to sit there and take a few seconds to resize the thing and while it’s not terribly inconvenient it is somewhat annoying. Can anybody help me out, please?

I also find this frustrating so if anybody has a quick fix it would really be appreciated.
