Been an issue for the past several years on my pc.  Click on help or the ? and BAM, programs crashes.  The forms bar causes issues too if I minimize the program.  When I restore ProSeries to full screen the forms bar will be black.  And as soon as I click it off under the "view" options the program crashes.  I just started ProSeries as "Administrator" in the Icon options.  Will try help and see if that helps.  In my opinion its a "graphics" issue.  But I could be wrong.  Ever since Proseries changed the help format a few years ago it started here.
