Minor adaptions in page layout:
WindowLineSpacing was used to establish a small separation from y0. This caused problems in string visualization (line > 1). To avoid the the window parameters have been adapted and WindowLineSpacing set to an value allowing two lines of data
Removed instrumentation for BigFon_V2
