Mouse Actions

• How can I display a dialog or popup-menu when the user clicked the right mouse button? (June, 13)
  
  
• Does OG support drag and drop from one cell to another (I don't want to use OLE Drag and Drop)?
  
  
• Is there a way of making the right mouse button act in exactly the same way as the left mouse button when clicking on a grid?  Thus the user is able to select a range of cells with the right mouse button etc.
  
  
• How can I change the mouse cursor on the fly while the user is moving the mouse over cells?
