Is this problem characterized by: 1. Create a plot in a cell 2. change the plotting code, evaluate the cell. Then maybe delete the cell. Save the worksheet and come back to it later. 3. Run a different plotting comand, or update a cell. When you evaluate the first time, the graphics are old graphics from other cells. Evaluate All refreshes the graphics, though. or something like the above? It seems like the root problem is something like #5177, where the old image stays around for longer than it should.
