are you getting any errors on editing the form?
saving the form settings as a preset?
No error. The padding element is just too stubborn. What I do is in Insert New Form>New From Blank. Then I customize all the elements. The padding element is just too stubborn. Whatever I change to the padding it keeps all to 5px.
I realize DW automatically open the all source code file including css in the tab. So what I do is I open blank page then I open Preset Manager, and create new preset from there, seems to work except this time checkbox and radio padding is stubborn, it keeps to 2px.
I use local testing server. The above problem appear both during preview and after finish (on web page).
