Does anyone know how to keep browser screen from scrolling in order to drag and drop

This has only been an issue since I finished my Fantasy Football draft on yahoo. On the edit roster screen to move a player to a different spot or bench you have to drag and drop them to that place, but all the screen does is scroll. I know there is an option to change to classic view and just have drop boxes but I like the drag and drop option. If anyone knows how to freeze the screen to select something that will be helpful. I am using the normal browser.
