Question / Help Docks aren't resize-able once docked?

[kenshinesca]

I made sure the option lock ui wasn't checked.

Is there some simple setting I accidentally enabled that made it to where I can't resize the docks once they're docked on the side/top panels?

Anyone know how to fix this?

I would like to know this as well.
