i dont know what i did, but when i right click on my mouse it opens my finder. When i log in, my finder does not start up like it usually does. So when i right click it opens my finder, and when i right click again, all the icons on the desktop dissapear for a moment then they come back, and it doesnt do anything, just focuses on the finder window. The bar up at the top will say finder, then disappear, then go back to finder. i looked at my mouse button shortucts in my expose folder in syst. pref. and none of them are set to anything. i try to right click a file like a music file or picture but the right click menu does not come up. all the icons disappear on my desktop then my finder folder opens up. whats the deal? how do i fix this?
