This is how Baseline Shift has always worked. In QuarkXPress 6.5 and earlier, the Baseline Shift value was not visible in the Measurements palette. To see how this works in earlier versions:

  1. Set your Baseline Shift value in the Character Attributes dialog.

  2. Click OK to close the dialog, Change the font size.

  3. Reopen the Character Attributes dialog, and you will see that the Baseline Shift value has changed proportionally.

The only difference in functionality in QuarkXPress 7 and 8 is that you can now see this proportional change of the Baseline Shift value in the Measurements palette as you change the font size.
