Snow Leopard and Extension Manager
I've been going round and round with Adobe's support about the fact that I get an incompatible file message when I try to install any WebAssist product except Sculpture 3 and Site Assist.
They finally came clean and said that Extension Manager and Dreamweaver are not fully compatible with Snow Leopard (something I knew) and they have no solution.
I have asked them when DW CS4 will be updated to support Mac OS 10.6 and have not received an answer (didn't expect one). Now I am stuck because I really want to use MenuWriter and other WebAssist products to speed prototyping and DW + EM 2.1 won't install the extensions.
