I play interactive games online and just yesterday, my mouse started acting strange, normally to move around my "town" I click and drag, now when I click and drag, when I let go and move my mouse, the town moves all around too like I'm still pushing the button.... I can't do anything this way.... VERY frustrating!! Please HELP!
Try to click again and move the mouse (you might have done that already).
may be there is a glitch in that game
is it happening every time ?
if yes, try reinstalling thr browser, most probably ,you might be using Chrome.
After reinstalling, update flash,java etc
