I upgraded my Galaxy S III to Android 4.0.4 last night and now I can't drag apps to the taskbar anymore.
Is there a setting I can change to be able to drag apps to taskbar again?
According to the User's Manual, there isn't a setting that locks the Primary Shortcuts. So I would suggest turning the phone off and then restarting it.
Here are the instructions from the User's Manual for Adding and Removing Primary Shortcuts. Perhaps there's a step here that you've missed.
