If this were happening to me I would try:
(1) Execute this command in the Terminal application:
defaults write com.apple.Dock contents-immutable -bool false
Did that help?
If not (or if Terminal stuff is too extreme for your tastes) I would try
(2) Delete the dock preferences (com.apple.dock.plist) in your HOME Library Preferences Folder and in the ByHost subfolder.

The terminal command approach will not erase your dock, but merely "unlock" it, if it is in fact "locked".
The deletion of preferences will put your dock in its default state and you will have to reconfigure it.
None of your files, applications, etc. will be deleted.

I had the same problem and only in my account. No problems with the other users on my computer. tried all the remedies above. Then I out of the blue, I turned off Time Machine and my dock worked fine. I turned Time Machine back on and it still works fine. I have no idea why that worked, but it did.

Thank you irwin305 for posting this. I was so frustrated with not being able to rearrange my icons in my dock, and turning off TimeMachine let me do it. How bizarre, but I am so happy that you provided the solution!
