Hi, I just recently downloaded Indesign and I haven't been able to drag or drop things.

I downloaded Indesign not too long ago for school reasons; and the only way I’ve been able to get things to move is by arrow keys. My selection tools don’t work (direct, and regular selection), and they don’t work even when I’m trying to make text boxes bigger and or more stretched out. I’ve seen this question asked before and nothing has helped. I have the latest version and everything.
