This morning I felt like playing Age of Mythology on the XP. The MacBook was asleep in Mac OS X and when it woke up, the mouse was frozen. This doesn't seem to be the case though when I use the trackpad. The external mouse I have is a Logitech Cordless Mini-Optical mouse(with a USB receiver) and it resembles the LX5 Cordless Optical Mouse (http://www.golem.de/0506/38366-cordless_mini_optical_center.jpg ). It's been little over a year old. Unlike the real LX5 model, it doesn't really have a connect button (atleast I don't think, I have no documentation of any sort with me right now). There is a reset button on the mouse's belly, but resetting didn't work either. This has happened to me a few times before but the rest button usually does the trick and it's never lasted for so long. I tried changing the batteries but the green LED button no the mouse keeps flickering so batteries isn't the problem. The external mouse's receiver even shows up in the USB ports on the MacBook and on the XP partition. I even tried cleaning the "invisible optic" with a Q-tip but it still doesn't work. I've unplugged the USB receiver and replugged it, and also restarting the computer hasn't helped either. Please help, I'm really distressed about this. I only have a week before back-breaking university homework starts again P.S.- Mouse came without any drivers or software and was fully Windows and Mac compatible. I think ti was working fine 2 or 3 days ago and since then I've left the MacBook on Sleep but I can;t remember if the external mouse was plugged in or not the entire time.
