Cannot Scale Fonts with Panel

Hello Forum,

I just decided to try using Adobe Encore as opposed to DVD Studio Pro (64bit, etc)

I am unable to change text kerning, height, tracking, etc using the icons in the font properties area.

This is the area, as in Photoshop CS6, putting the mouse over a "T" and you can change height or width by moving the mouse left or

right or up and down.  This works great in photoshop. The only way I can change text height or text in a button, is to type a value

in the box, like 150% instead of 100%.  How can I get those controls to work?

Thanks
