I'm using apple quicktime, and it isn't working for me. Which is surprising, because that's what Firefox recommended...

Intermission -- Events

1. Define an Event class. Specific kinds of events can be subclassed from this base class.
2. It should have at the very least a property to track the event's location on the map. Point or pair of ints, doesn't really matter here.
3. Add to the map editor a List<Event> variable to store them in.
4. Add an EventBackbuffer and EventGraphics object. This will be used to draw the events on, in a transparant image.
5. Add FinalBackbuffer and FinalGraphics objects as well. The basic idea is to draw the map and events on seperate layers, then simply merge them onto the final layer and show that. Makes changing their contents faster, since you don't have to worry about redrawing the one when you change the other.
6. Add a "currently holding" variable of the Event type.
7. On mousedown, set "currently holding" to Null and iterate through the events list, comparing coordinates to the cursor's. If you find one, set the currently holding var to that Event and stop. I suggest using an "event mode" bool here.
8. On mousemove, if the currently holding var is not null, set its' position to the cursor coordinates and call your Event Redraw function.

Part 2 - Undo Buffers

	//One single change of the map
	class TileChange
	{
		public int X { get; set; }
		public int Y { get; set; }
		public int From { get; set; }
		public int To { get; set; }
		public TileChange(int x, int y, int from, int to)
		{
			X = x;
			Y = y;
			From = from;
			To = to;
		}
	}

	//One "brush stroke" worth of edits, from mousedown to mouseup.
	class UndoState
	{
		public Bitmap Before { get; set; }
		public Bitmap After { get; set; }
		public List<TileChange> Changes { get; set; }
		public UndoState()
		{
			Changes = new List<TileChange>();
		}

	Stack<UndoState> UndoBuffer = new Stack<UndoState>();
	Stack<UndoState> RedoBuffer = new Stack<UndoState>();

		public void StartUndo()
		{
			RedoBuffer.Clear();
			NewUndo = new UndoState();
			NewUndo.Before = (Bitmap)MapBackbuffer.Clone();
		}

		public void AddTileUndo(int x, int y, int from, int to)
		{
			NewUndo.Changes.Add(new TileChange(x, y, from, to));
		}

		public void CommitUndo()
		{
			NewUndo.After = (Bitmap)MapBackBuffer.Clone();
			UndoBuffer.Push(NewUndo);
		}

		public void Undo()
		{
			if (UndoBuffer.Count == 0)
				return;
			UndoState ThisUndo = UndoBuffer.Pop();
			ApplyUndo(ThisUndo, false);
			RedoBuffer.Push(ThisUndo);
			mapPictureBox.Refresh();
		}

		private void ApplyUndo(UndoState buffer, bool redo)
		{
			MapGraphics.DrawImageUnscaled(redo ? buffer.After : buffer.Before, 0, 0);
			foreach (TileChange c in buffer.Changes)
			{
				int x = c.X;
				int y = c.Y;
				int tile = redo ? c.To : c.From;
				if (x < 0 || x >= MapWidth || y < 0 || y >= MapHeight)
					continue;
				Map[x, y] = tile;
			}
		}

• Unhook the mousedown event handler and make a new one. It should check for pressing the left mouse button. If so, call StartUndo, then call mapPictureBox_MouseMove with the same sender and eventargs.
• In the mousemove event handler, before making the actual changes to the map data, call AddTileUndo(x, y, Map[x, y], CurrentTile).
• Add a mouseup event, again checking for the left mouse button. If so, call CommitUndo.
• Add two controls (menu items preferred) to call Undo and Redo with. For added bonus, you can disable them easily with, for example, undoToolStripMenuItem.Enabled = (UndoBuffer.Count > 0);

The if this board had image attachments for this, I would add an image of the compression method that is used just for those games, given that if I had posted a image of this fixed width format, then we would get the idea of it
