First, Be sure to save your theme before doing all of this.
Please unload/quit ObjectDock so that it is not running, and then go to Start > Run... (Start > Start Menu Search in Vista) and then copy this into the command line:
for XP: %userprofile%\local settings\application data\stardock
for Vista: %userprofile%\AppData\local\stardock\
It will open a file folder. Delete any ObjectDock or ObjectDock Plus folders. Then restart ObjectDock, this should clear your issue.
