I am using a Mac Pro4, Quad-Core Intel Xeon 2.26Ghz 16GB ram OSX Snow Leopard 10.6.3
Using Adobe CS4 Suite, Dreamweaver CS4.
I regularly repair permissions.
I often have problems with the Webassist extensions, the cart set up etc. Tabbing from one item to the next does not save any selection, I must do it all very precisely, the wizards are always giving me problems. Sometimes I cant save what I have done because it ask me to fill in the details of a dialogue box that already have an input, I need to hit enter or return on many thing to have them accepted only to find on occasion that this finishes the edit and the dialogue extension closes. Trying to edit some pages with the wizards is difficult as they add the code to the page a second time, there is now way to edit the existing code in any structured dialogue box, only manually in code view.
There is no way to edit the details of the checkout wizard without starting over again and you end up reproducing all the checkout pages again.
In general I find that not many things work first time, they always seem to add unusable code that restricts the proper use of the extension. UEmail 4.0 an example.
The offending js file on one site worked ok on another web site.
