I am using a trackpad and magic mouse with my i5 mac-mini. Both were working fine but after coming back from holidays after two months I observed that the magic mouse is not working properly. The top side of the magic mouse works properly and I can navigate the web pages from side to side or scroll vertically with the top portion of the mouse. However the bottom part does not work on a mac. I cannot select any object and click with it. I tried to clean the bottom lens and it does work sluggishly on a Windows PC but however it does not work on a mac. I have charged the batteries to 100% but still the problem persists. Kindly help.
