Changed SelectedPath = @"apps" to SelectedPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, @"Reports")
replaced: Environment.SpecialFolder.DesktopDirectory with Environment.SpecialFolder.MyComputer
Mono doesnt work well with RootFolder of DesktopDirectory, you end up being stuck in ~/Desktop/. Instead when being run under mono use MyComputer, which dumps you to /
