Hello,

I have an interesting problem that I can¹t work out.

I have a GUI app that uses FolderBrowserDialog. It works fine when I run  
it  
from the command line with ir.

When I embed IronRuby in an app, the browse window comes up, the ok,  
cancel,  
and make new folder buttons are there, but the actual browse  
functionality  
is missing. It¹s just blank where the browse bit should be. This is how  
I¹ve  
called IronRuby from the app:

ScriptRuntime irruntime = IronRuby.Ruby.CreateRuntime();

```
        ScriptEngine ir = IronRuby.Ruby.GetEngine(irruntime);

        ScriptScope scope = ir.CreateScope();

        ScriptSource script = ir.CreateScriptSourceFromFile(script);

        script.Execute(scope);
```

I seem to recall that the actual folder brower is implemented via COM,  
and that you probably need an [STAThread] attribute on your Main method.
