Selection struggles

I haven’t ever had this problem before, but it’s been so frustrating! Usually, you can just click and drag from top left to bottom right to select multiple things in Rhino. However, when I try to do that it is not working! I am just getting a line (see picture) and can’t move anything. Nothing is locked so I’m just really confused what the deal is. I read on another thread to drag select while pressing the alt key and I tried that and it looks like it works and I can draw the selection rectangle but it won’t actually select anything.

Hello- it looks like at least one object is selected - to force a window selection without actually selecting anything on the first click of the window, hold the Alt key down.

Does that do anything good?
