Hi, I have a problem with random "color blocks" appearing on the screen when using the Windows browser. They never happen with any other program on the computer so it is only an issue with the browser. These color blocks usually disappear when I roll the mouse arrow over the discolored block or reload the page. I have attached an image with an example, you can see the discolored black block when it is supposed to be all grey. I have tried both refreshing and reinstalling the software. The software has worked on this computer before. Any help would be appreciated. Kind regards, Magnus
