Fw: Re: DifferenitalD vs CapitalDifferenitalD

After applying Jens correction, I was hoping to be able to use the 
DifferentialD  with x, etc. and then use the 'dx' , where 'd' here is 
DifferentialD (just dont know how to add it here in the email),  so it 
would be a Symbol....but this didnt work....I realize I can use the 
straight forward   dx , etc.  symbol but I want to highlight the 
Differential....any way to 'fix' this?....when I type in  DifferentialD 
, from the Palette, and then add x to it and perform  //Head on it , it 
just returns DifferentialD

thank you....jerry blimbaum

Hi,

this is a bug, add

MakeBoxes[DifferentialD[x_], fmt_] :=
  RowBox[{"\[DifferentialD]", ToBoxes[x, fmt]}]
