I use My Editor by Wings to view and edit my designs. It's a free download. Thumbnailer by Embrilliance is great to have to see the designs on file in your computer folder. I think it's about $49. I have a PE770 but have upgraded to a Brother/Innovis NQ1400. One of the biggest reasons I upgraded was the difficulty in viewing the designs on the screen. Like Sewnoma said, the resolution makes it hard to see the detail especially when you have similar designs and are trying to find the one you want.
