so i just updated to version 3.5.2 today.
i have discovered that the ability to choose whether to resize a layout element proportionally or not, has dissapeared.
the option is still there for map windows or scale bars, but all text boxes and layout elements no longer allow dissproportional resizing. incredibly annoying.
the first image is how these element properties look today, and the second image is how they were last week. note the lack of the little icon to choose proportional resizing..
