It would be ideal if the Margin Left, Right, Top and Bottom fields within the layer Properties window permitted the use of the -(minus) symbol, as this is frequently used to help position some divs within pages. I am presently having to access the code view to to enter these dimensions as the fields only appear to accept numerals. The - symbol then displays within the relevant field when the Properties window is re accessed even though the symbol cannot be entered there.

 

Thanks
