RE: [ROOT] Problem with #int & #sum in Latex

The problem seems to be in the text extend we get with symbol characters 
(I will investigate that on windows to be sure). When you create text with 
TLatex, each piece of the text is positioned by the TLatex class itself 
not by PostScript. So if the text is wrong on the screen it is also wrong 
on the PS file.
