I have found that when I try to vertical scroll by swiping my finger vertically on the Magic Mouse, it sometimes hangs. The to get it to scroll, I have to manually scroll. Than sometimes scrolling works. Also, I find under certain conditions when I move the mouse pointer to a new location, the mouse moves, but the pointer lags for a fraction of a second. This problem is intermittent and sometimes the scrolling works perfectly and I can control the length of the scroll just using my finger.
I submitted the same problem on Apple's support page but have yet to get an answer. I cannot call Apple Tech support as the mouse is not covered under Apple Care.
Any ideas?
