I'm using CSSsculpter and using the 1column fixed centered header and footer and Cabo sunset. If I create an element and add margins, save a preset and than re-enter site sculpter the margins of the element appear in the tree, however once you click on the element in the tree some of the margins are not in the drop down menus if you click another element the margin dissappears from the tree.
This appears to happen only when entering -value px.
Another Issue, just turned up...I add a div however instead of selecting the newly created div it's selects another div further up the tree (while still highlighting the new div) i.e. change the name or settings of the new div, it changes the name and setting of the div further up the tree.
If you chose not to change the name of the newly created div and leave it at the default (i.e. Div) , CCS Sculpter changes the name of the div further up the tree to Div2.
