First off it's been about four months since I setup a permalink to any form for public access so I realise the interface for this specific instruction set has changed in that time.
OK so from my form I select Permalink and in the dialogue I select Publish, to make it public then hit Customize. I'm dropped back to the editor window and am shown a preview which updates as I change fonts, fields sizes, etc within the customization pane on the right side of the browser.
The problem is the Publish URL listed above the live preview doesn't update when I make a change to any details! Why is code such as 'zc_BtnFontSize=16pt&zc_LblFontSize=12pt&zc_InpFieldFontSize=12pt' not updated in the URL?
