Unable to move my WoW interface windows

[Narandel]

Hi forumers, it seems that i have this problem of not being able to move multiple world of warcraft interface windows. For example, i am unable to move around my character window, social window, dungeon finder window, quest log window, achievement window etc etc. I do not know why this is happening. Ive tried disabling all the addons which i am using and it doesnt seem to help at all. Anyone able to help me solve this problem? And the i cant seem to move my chat bar even though it has been unlocked in the world of warcraft interface section.
