When I load up Vegas Movie Studio the text scaling is all screwed up. You can see this on the splash screen above. The text is also very large in the editor which makes editing a challenge:

I've tried messing with graphics settings, scaling settings in Windows, resolution etc but can't sort it. Movie Studio is the only software that is having this problem.
