- open the MITK workbench (without any image loaded -> ImageNavigator should be disabled)
- go to Preferences -> Editors -> Standard Multi Widget and enable "Use PACS like mouse interaction [...]
- use the PACS Mouse Mode Bar beneath the render windows to switch to "Scroll"-Mode (second icon)
- hold the middle-mouse button and move the mouse to perform the scroll-action
-> MITK will freeze because of an infinite loop inside `mitk::DisplayInteractor::Scroll`
This happens because the 'autoRepeat' mode tries to wrap around the image slices if the minimum or maximum slice is reached. However, in this case it will never be able to find a slice "in between".
