Are you able to open/close/move all the respective panels manually?
Are Photoshop and OS fully updated and have you performed the usual trouble-shooting routines (trashing prefs by pressing command-alt-shift/ctrl-alt-shift while starting Photoshop until the appropriate dialog appears after making sure all customized presets like Actions, Patterns, Brushes etc. have been saved and making a note of the Preferences you’ve changed, 3rd party plug-ins deactivation, system maintenance, cleaning caches, font validation, etc.)
Sound like a workspace file is corrupt. Shutdown Photoshop. Find your user ID Photoshop modified workspace folder and delete or rename the essentials file. Depends your environment where that file is on a windows 7 system mine is:
"C:\Users\John J McAssey\AppData\Roaming\Adobe\Adobe Photoshop CC\Adobe Photoshop CC Settings\WorkSpaces (Modified)\Essentials"
