I recently downloaded and used the SD Formatter app from the SD Association web page. I was formatting several 32 gig cards. I noticed that some time into the formatting process my left mouse button stopped functioning on the magic mouse. After some fiddling around with settings and not getting it to work I dug out an old USB powered mouse, only to discover it wouldn't work either. After getting my system to reboot the mouse worked fine, but I then tried to format another SD card and the mouse problems returned. Has anyone seen or heard of this type of issue before? Is the app corrupting the mouse kext?
