P: I can't adjust the size of paragraph text bounding boxes

Sorry to hear that this has happened. Could you tell us more about this issue. We are trying to figure out if it is a bug. 

Does the cursor change to double-head arrows when hovering over the bounding box? If it does, what happens if you click and drag? 
Alternatively, it would help if we could see a short video showing the issue.

Could you also share your system info? That is under the Help Menu and then System Info. 

Thanks, 
Catherine
