When resizing paragraph text, the default is that the shape size changes, but the text properties stay the same, so if it was a 12 pt before, it will be a 12 pt after.
IF you hold ALT while resizing, it will reduce the size of the text and move tabs so that it gives the same appearence as before. This is great. A 12 pt might be reduced to an 8 or 6 pt or less.
BUT if you select the paragraph text with a bitmap OR an Object that completely overlaps it. Holding alt looses the ability to maintain perspective and proper proportions.
I can reproduce on video if you need me to.
