I have 6 picturebox controls and load each of them with a command button control array. The zorder at design time of the picture boxes is 5 to 0 and the corresponding control index is 0 to 5 connecting to the corresponding command buttons 0 to 5. When i click command control button 0 the picturebox being loaded flickers and the background show through. It also happens at some other points in the app. How can i stop the flickering?
