Hi folks, This just started happening today on my (old) 12" PowerBook, and it's difficult to describe, but I'll try my best. Basically, it seems as if my left mouse button is stuck on some sort of turbo mode. If I press the left mouse button, it will repeat the left click action very rapidly until I let go. This makes some things like dragging, highlighting text, etc pretty much impossible. For example, if I click on the title bar of a window to move it, when I start dragging the mouse, the window minimizes. In addition to this, my trackpad is messed up. If I move my finger from one side of the trackpad to the other, the pointer will move perhaps 1 cm on the screen. When I take my finger off the trackpad, the pointer will snap back to where it was before I started moving it. This happens whether or not I have my Apple Pro mouse plugged in, or my Logitech MX700. I did not change anything that would cause this to happen, and I've tried the obivous things like downloading Logitech Control Center, disabling USB Overdrive, rebooting, etc. Any ideas?
