Hi, Laurence. I have also seen this problem.When you go into Move mode, a handle appears at the right hand end of each task. At the same time, a scroll bar appears at the right-hand edge of the screen. The scroll bar is a super-thin black line, with a slightly thicker black handle. The thin black line crosses in front of the move handles, making it impossible to actually touch the move handles. When you try to touch the move handle you are actually selecting the scroll bar. The scroll bar is only displayed for a short time. On my Samsung Galaxy Note II it shows for maybe three to four seconds. On some models of phone it displays longer or shorter times, depending on the phone's processor speed and maybe other factors. So, when you go into Move mode, look for and find the thin scroll bar. Wait until it goes away. Now try moving tasks, it should work.
