Please can anyone help, i work in a cancer esearch lab and we have both numerous Macs and PCs and often transfer presentations between them. However, when going from PC (XP or 2000) the Y axis of all graphs (either drawn in excel or Prism) in a powerpoint presentation get completely messed up, each character in the axis label is seen seperately, rotated 90o clockwise and thus making the axis label nonsense. Any attempt to correct this on a mac in ppt by ungrouping just causes further problems. Also, this happens no matter which method the graph was inserted/copied into ppt and grouping or pasting as a picture do not prevent this! When going from Mac to pc the y axis (excel drawn graphs) dissapears, this can retrieved by double clicikng on graph to open exel once on the pc, but again this can introduce random changes. The other problems with have are speical characters (i.e. ß) and also bullet point symbols change when ppt presentations are moved between Macs and PCs. Has anyone any idea what we can do to minimise these cross platform issues??? Thanks Simon
