I have an eMac G4 running OS X 10.2.8. My problem is I can no longer drag and drop icons on my desktop or from anywhere else for that matter. I suspect a friend of mine while on my computer went into the preferences or system folder and somehow changed a setting that prevents the drag and drop option from working. I can work around this problem but it sure would be nice to have the option back. Can anyone walk me through the steps to correct this problem?
