My mouse has a icon... and it won't let go!
This is really the weirdest thing, but when clicking and dragging something (Pages, Keynote, icons & folders around the desktop) it shows a light shadow of what I am moving under the mouse arrow. Normally, when I let go or release the click the shadow disappears and drops the dragged item where it is supposed to be. What's happening now is it hangs on and won't go away. I can move my mouse all over the place and the shadow is stuck to it like glue. This has never happened before and am wondering if there is a software flaw of some sort or is my settings just messed up.. or... did I do something like Microsoft's "Sticky Fingers" and click shift 5 times and cause this to happen? If so, how in the world to I get it to stop? The only way I can get it to let go is to power the computer off which stinks when working on large projects. Any help would be greatly appreciated!
