You still can, you just need to do this from the GUI thread.  We will
need more information about the circumstances you are doing this under
to help.  Can you paste your code?

Sure, no problem. Though I don't know if I should post the whole one ore not ^^. anyway. here it is :

        protected virtual void OnCovertClicked (object sender, System.EventArgs e)
        {
                try
                {
                this.SelectFolder.Sensitive = false;
                this.FileAdd.Sensitive = false;
            this.RemoveFile.Sensitive = false;
                this.ClearAll.Sensitive = false;
                this.entry1.Sensitive = false;
                this.combobox1.Sensitive = false;
                this.combobox2.Sensitive = false;
                this.menubar1.Sensitive = false;
                       
                selectedFile = String.Empty;
                newselectedFile = String.Empty;
                oldselectedFile = String.Empty;

                while(this.menuListStore.GetIterFirst(out iter) != false)
                {
                format = this.combobox1.ActiveText;
                quality = this.combobox2.ActiveText;
                iter = new TreeIter();
               
                menuListStore.GetIterFirst(out iter);
                selectedFile = (string)menuListStore.GetValue(iter, 0);
               
                if(selectedFile.Substring(selectedFile.Length -4) == "flac") number+=1;
                               
                oldselectedFile = selectedFile.Replace(selectedFile.Substring(selectedFile.Length - number), format);
                selectedFile = selectedFile.Replace(" ", "\\ ");
                newselectedFile = selectedFile.Replace(selectedFile.Substring(selectedFile.Length - number), format);
                               
                if(selectedFile.Substring(selectedFile.Length -4) == "flac") number-=1;
               
                string command = "ffmpeg -y -i " + selectedFile + " -ab " + quality.Replace("b/s", " ") + newselectedFile;
                                       
                if (System.IO.File.Exists(oldselectedFile))
            {
                        MessageDialog md = new MessageDialog (this,
                                                      DialogFlags.DestroyWithParent,
                                   MessageType.Question,
                                      ButtonsType.YesNo, newselectedFile + " already exits. Overwrite it?");
                       
                        ResponseType result = (ResponseType)md.Run ();
                       
                        if (result == ResponseType.Yes)
                        {
                        md.Destroy();
                        this.Convert.Sensitive = false;
                        proc = Process.Start(command);
                        }
                        else
                        {
                        this.FileAdd.Sensitive = true;
                        this.Convert.Sensitive = false;
                        md.Destroy();
                        }
                }
                else
                {
                this.Convert.Sensitive = false;
                proc = Process.Start(command);
                }
                this.menuListStore.GetIterFirst(out iter);
                this.menuListStore.Remove(ref iter);

                }
// GLib.Idle.Add(delegate {
// if (proc.HasExited) {
//
// MessageDialog mdg = new MessageDialog(this, DialogFlags.DestroyWithParent, MessageType.Info, ButtonsType.Ok, "Encoding finished");
// mdg.Run();
// mdg.Destroy();
//        
//        return false; // Remove this delegate from the idle list.
//    }
//
//    return true; // Run this delegate again when idle.
//});
                proc.EnableRaisingEvents = true;
                        proc.Exited += delegate {
                                Application.Invoke(delegate {
        MessageDialog mdg = new MessageDialog(this, DialogFlags.DestroyWithParent, MessageType.Info, ButtonsType.Ok, "Encoding finished");
                mdg.Run();
                mdg.Destroy();
    });
};

                       
                this.FileAdd.Sensitive = true;
                this.Convert.Sensitive = false;
                this.SelectFolder.Sensitive = true;
                this.entry1.Sensitive = true;
                this.combobox1.Sensitive = true;
                this.combobox2.Sensitive = true;
                this.menubar1.Sensitive = true;
                       
        }
                catch(Exception ee)
                {
                        Console.WriteLine(ee);
                }
        }


In my eyes it's very ugly code and beside my problem here I would appreciate any suggestions ;)
Thx :D
