Maybe code such as this will serve your purposes.

//subscribe to the event is form load
this.VisibleChanged += new EventHandler(Form1_VisibleChanged);

//the event handler checks to see if it is on the proper thread and if
not, does an Invoke to come back in on the proper thread.

       void Form1_VisibleChanged(object sender, EventArgs e)
       {
           if (this.InvokeRequired)
           {
               this.Invoke(new EventHandler(Form1_VisibleChanged),
new object[] { sender, e });
           }
           else
           {
              //do whatever your want on the form's thread
           }
       }
