PhotoView Interface Issues

I'm having some issues with my interface in PhotoView 360.Somehow I lost everything from the Materials advanced tab. It isblank until I click on a part, then I only get the properties (seeimage), with no color chooser area above. This happened in themiddle of making some adjustments. I think I hit some keysaccidentally, but I don't know which ones.

The screenshot also illustrates another annoyance. Notice that Ihave about 1-1/2" of blank grey between the image area and themenus. I cannot get rid of that. If I try to drag the top edge ofthe graphics area, only the sphere images at the top get smaller.

Any suggestions, or is anyone else experiencing this?SolidworksPhotoview 360
