Open new
Open Text/Text and Font side panel toolbox - not sure of actual name -.
Click Text button on left side toolbar.
Click on drawing area and type.
Click on another font in side panel toolbox and press Apply, and it works fine.
Now click on arrow of Font size drop down menu in Style and select another font size, and the Apply doesn't highlight to apply the change.
That selector doesn't seam to work, you have to use the top Text toolbar to get it to change.
