I have been using the older android 4.2 and 4.4 boxes for years, and now I have moved up to the 7.1 and higher ones, but these new boxes have an issue with scrolling on apps such as Mega Box Hd, Terrarium TV, and Morpheus. When the app loads if you try to scroll with your mouse after about 4 lines of movies the mouse jumps back to the top of the movie list. This happens on the three apps listed above. If you use the remote hand unit it works fine. There are no mouse issues if you are in KODI. All addons scroll properly like using the older 4.2 and 4.4 boxes. I thought the newer boxes would have more advanced features, but it appears they are taking a back step in the way they perform. I don`t like the fact that If I am using the mouse I have to push it aside and start using the hand controller for a few apps. Anyone that might shed some light on this problem would be much appreciated, and if there is a fix for the mouse scrolling issue I would be pleased to here about it. Thanks
