I thought I read somewhere that they will allow for multiple shows to be playing at one time in future versions of VG/DB. For the longest time I was able to open multiple instances of the program to artificially create this but with recent patches removing this I was stuck with only one show at a time. Until they patch said fix I wanted to share an option to allow for multiple instances of VG to be open at the same time.
You can download Sandboxie, (The link is easy enough to find) and run it in sandboxed mode. If you're not sure what sandboxing is, don't fret, it's not a difficult program to install. I also have no vested interest in this company so feel free to make other suggestions. I just wanted to share as I enjoy having mulitple shows going at the same time. (One of the many benefits of multiple monitors.)
