Nubie troubles w/ first CSS form

Side question... I suppose since the WebAssist stuff is primarily extensions, the chunky/choppy Dreamweaver execution is to be expected? But I am getting a number of L O N G pauses and some flat-out lockups. Is there something simple to avoid this?

The real question for this post... Once I create a new CSS form, I cannot get back in for editing. Scenario: New PHP Page in DW. Save it. Open it. Insert CSS Form-> Registration-> Simple Registration. Design->Standout. Save it. Open it and try to “click inside the form and choose WebAssist->CSS Forms Builder->Insert Form. Every time I do this, no matter where I “click inside the form”, I get the “new form” mode with no preview of the existing form. I know this editing workflow works because I can open and edit many of the canned WA forms from the User Registration Prebuilt Solution.

TIA
