Just a tip : If you are struggling with the "size" of the fonts on your timeline, go to Display settings and change the fonts used to a larger size. Just done it. World of difference!
In doing so, realize that it may mess up several plug ins and interfaces to not just Vegas, but if you have Word, Excel, Sound Soap, Macromedia products, etc, you'll see problems there too. Partial display of dialogs is what you'll see in many instances,
so adjust at your own risk.
In Windows go to "All Programs - Accessories - Accessibility - Magnifier" I sent the thing to desktop shortcut. Just a tip from the AARP Windows User Group Forum thingy. Darryl
