10.7.4 updater left invisible dock url icons
After running the 10.7.4 combo updater on my10.7.3 iMac, the 5-6 URL icons (the @head key icon) on the right side of my dock have all becom tranparant or invisible. I can still click on them and see the web page title associated with each and they tell Safari the proper url address, but although they take space on the dock you see no icon image!
Repairing disk permissions did nothing. Going to download a new copy of the updater and run it again to see if that helps. Apple support had me delete the dock.plist file but that did not fix the problem as dragging a url from Safari to the dock still results in an invisible but functional icon.
Any ideas?
