Text resizing not working

I hope I am in the right place. Am working on my first project and the text resizing is not responding. The two lines and two squares are there but when I try to resize the type I move the square but it snaps right back when I release my mouse button. Even though the square moves the type never resizes.

I have no idea what happened but after making the post I reopened the project and the text resizing was working fine. If anyone else has had this problem I would like to know if it has happened more than once and if so is there a fix.

Thanks, Clyde
