Why can't I adjust the scale of my text by clicking and dragging the corner boxes?

I just had this problem. I was trying to resize a several texts in my design and noticed that other fonts can be resized by the bounding box and the others cannot.

What I found out was that the OTF can be resized using the bounding box and the TTF won't work.

I am not sure this is the answer? There is something that gets triggered from time to time that makes my text boxes stop responding to regular commands with the selection tool and ST and command to scale the text. I am not sure what it is or what I hit but its super annoying. Now to even manipulate the box at all I have to use the Direct Selection Tool and grab the stupid corners over and over again. So, something happened.

When I hover over the corner with the selection tool just the black top of an arrow shops up with a timy hollow square just to the bottom right of it. thanks again

I tried the Ctrl B and nothing seemed to happen.  Normally there are more than four handles, usually some on the sides, not just the corners. Here is a screen shot. Normally I should just be able the grad a corner and size handle and click and drap to change the size, rights? It won't let me, all I can do is move it around the artboard.  Thank you for your help -max

You should be able to resize it by clicking a corner node and dragging it with the Selection Tool, which is the black arrow. Can you post a screenshot of what you see on screen? That may help us to identify what the problem is.

Have you accidentally hit Cmd(Ctrl)-B which is the toggle for Show/Hide bounding Box?
