How do I make the Text Media Edit box bigger?

Hi, so when I make a new Text Media event and look in the Video Media Generators window in the Edit tab, it shows a small text window-in-a-window that takes up but a small part of the whole window. No matter how big I resize it, the area where it says "Sample Text" stays small and isn't fully viewable.

(This is difficult because it makes me scroll around a lot more with subtitles than I would have to if the text field was bigger.)

Is there a solution/workaround to this? I'm in Vegas 8 and these are for simple titles, so I don't need the Pro titler.

Gratitude in advance.
