I recently upgraded my RAM on my iMac G5(no camera), running OS 10.4, to 2gigs. Now, whenever i click on any of the icons on my dock that are located on my external hardrive, a whole new icon appears on the right side of the dock and starts bouncing. The icon that i originally clicked on does nothing. So it is like the wrong app opened. If there is anything you can think of to help me please tell me what it is. Thanks.
