I'm running 10e on a win7 64 bit system. I've customized my toolbar with a few buttons that I use frequently--mostly scripts like deshaker and functions from Vegasaur. When I first open Vegas, all toolbar icons are visible. However, after editing a while, these custom icons disappear ( I don't know exactly when they disappear). I can move the cursor over the now blank area and the pop-up boxes appear and the functions still work--just the icons are no longer visible. Not a showstopper, but more a PIA. Any ideas?
