does any one get this? I can be stiing doing a crossword puzzle and just holding my hand still thinking, and my hand will jerk and scribble on the book. Ive also been finding when I type, a lot of the time I can't seem to type the correct letttes, and that is for writing by hand also. I do alot of correcting. Im starting to worry that there may be something more wrong in addition to the FM. any thoughts?
