I've tried many different approaches to solve this issue but none have helped. Some environment information:
- running OSX 10.9.1
- use an external monitor
Look forward to your suggested fixes.
For EM CS6, please delete "/Users/<YourUserName>/Library/Preferences/Adobe/Extension Manager CS6/exman_uiPreferences.xml". For EM CC, delete "/Users/<YourUserName>/Library/Preferences/Adobe/Extension Manager CC/exman_uiPreferences.xml".
The "/Users/<YourUserName>/Library" folder is hidden in Finder. You have to hold down "option" key when you click the "Go" menu in the top menu bar, then click "Library" in the dropdown.
Thanks Carl - that corrected the issue.
