Hi,

The method NSApplication#beginSheet... is asynchronous. You not need
to create a new thread.

I wrote a testing app and it works fine.

controller class:
----
class AppCtl < OSX::NSObject

  ib_outlet :window, :sheet
  
  def showSheet(sender)
    app = OSX::NSApplication.sharedApplication
    app.beginSheet(@sheet, 
      :modalForWindow, @window, 
      :modalDelegate, self,
      :didEndSelector, 'endSanmpleSheet',
      :contextInfo, nil)
    # wait...
    (1..3).each do |i|
      p i
      sleep 1
    end
    app.endSheet(@sheet)
  end
  
  def endSanmpleSheet
    @sheet.orderOut(self)
  end
  
end
----

NSApplication#endSheet does not close the sheet. We must call "orderOut" 
of the sheet in delegate method.
