Use the DataManager to turn „rgbImage“ visible and „ramp“ and „rgbaImage“ invisible; test the LevelWindow
**Expected Result**
Only the image „rgbImage“ is visible and the displayed color range changes in accordance with the setting of the LevelWindow Slider.
**Observed Result**
Also after sliding the LevelWindow Slider around too many times at extreme ranges makes MIT K crash :(
