so this problem just cropped up a couple of days ago and i don't recall doing anything out of the ordinary to cause it to have happened, but here goes:

all of my manipulator tools (move, scale, rotate, etc) are huge. i can't select any of the manipulators (the squares on the scale, arrows on the move, circles on rotate) because they're not in view. here's a screenshot of what the rotate tool looks like. the red and yellow axes going through the screen are supposedly the rotate manipulator. when i zoom all the way out the tool stays the same size and i can't zoom out far enough to get the circle to come up. has anyone ever seen this before or know how to fix it?
