I just installed the Google Maps extension in Dreamweaver CS6 (on a Mac). It shows within the DMXzone Updates, in teh Adobe extension manager. I registred my version without any problem... but I cannot find the DMXzone extension in Dreamweaver.
Where should it be...?Under Extension I only find the Adobe browser lab.

Oh yes, I restarted Dreamweaver a couple of times

OK... I found it.
Sorry
