line width in ps files

    Hi,
     I have the problem that any linewidth but the standard one does
     not get accepted by postscript.
     I have hists and I change the linewidth by clicking on the hists
     and using the SetLineAttributes option. The line gets changed in my
     canvas, but when I save that as a ps file, the linewidths get
     reset.
     Any suggestions?
     
     Also: I would like to plot data points with errors and I use
           the option 'gr' and TGraphErrors. This way the displayed
           graph does scale the frame properly. Some of my error bars 
           are displayed in a way that they exceed the frame.
           Is there an easy way to preset the scale of my x and y axis?
           
      
      As always, thanks for your help and support.
      
      Wolfgang
