DMXzone Extension Manager Version 1.1.0 (1.1.0) refuses to close before I shut down my mac running OS10.9.5, I either have to force quit or "retry" closing to get my machine to shut down. This can't be right, matter of fact I have to force quit to get this app it to shut down, it won't quit without doing this. This can't be "normal" .

Hi Gary,
Please go to: www.dmxzone.com/go/22670/dmxzone-extension-manager-for-dreamweaver then download and install the latest version: 1.1.2 this will most probably fix the issue you are having.

I installed the update and now my slideshow is broken, and no inline property inspector! What should I do?

Could you please be a little more detailed? What exactly the issue is and which is the extension you are referring to?
