Preview does not display in CSS Sculptor, Theme-it, SiteAssist Pro
Preview was enabled so sorry I didn't mention that.
Yes, preview in browser does work but that is obviously a complete pain working that way.
When openning in a browser the link/address shows as:-
file:///C:/Users/Kym%20Harper/AppData/Roaming/Adobe/Dreamweaver%20CS4/en_US/Configuration/Shared/WebAssist/Preview/wa_managetheme_mc.html
