Describe what you noticed and did

1. Create default sandbox
2. Set admin rights for sandbox (drop rights from Administrations; make applications think they are running elevated) in admin rights tab
3. install signal in sandboxie
4. cannot open signal

try to open in cmd from from windows (outside sandboxie) - doesnt' work:
