152: Display - interference lines on the screen

Black and white interference lines or bands appear on the screen sometimes on some Dell models and some other computers, particularly when Properties panels are open. It is a fault with the video card driver – not caused by Sibelius (some other graphics-intensive programs are also affected). Upgrading your video card driver software to the latest version usually solves this problem. If not, you may find that changing the number of screen colors solves the problem.
