Dreamweaver CS4, OS X 10.6, and Extension Manager 2.1.115

...they absolutely hate each other.

None...NONE...of my extensions work now.  I can 'install' them with EM but the moment DW is started they not only show up, but when I returned to EM, they are (if EM was closed) no longer open, or (if EM was still open), there but not showing up in DW.  I'm told (obviously) that I must restart DW.  I do this, but still nothing; the extension(s) are not appearing anywhere.

If tried everything I can think of having searched multiple threads all over the place.

It seems to be an issue between OS X 10.6 and Extension Manager.

Anyone experiencing the same?  Anyone find a solution??
