This is probably a really simple fix, but I cannot figure it out, and neither can Snaf. I took a sample picture of it to help people along.

As you can see i made a simple 100x100x100 box and selected the "select and move" tool. Also, if you haven't noticed by now, the little colored lines whihc you select to move and object (red, green, and blue) are very tiny.
This has been happening for a little while, and now i just gave up on trying. It takes multiple tries just to move the object the way i want to.
I'm also going to add that zooming in or out has no effect what-so-ever.
My question is, how do I get it to its original size.
I'm also going to ask that nobody posts here just saying "I have no idea" or "thats tough" or "hahaha, Pie needs help now" or anything of that sort. I would appreciete only posts concerning this problem and a possible solution or advical statement
