Dear all, especially Bernard and Andrew, I found some subsequent information that could be meaningful, at least to anyone who has considerable more knowledge than me. As said, !PhotoDesk loads without any problem, after running !Printers first. However, when I try to choose a different printer after loading !PhotoDesk, an error box pops up, saying: Internal error: abort on instruction fetch at &21DF2DFE in "squished.SupportPS" (&80000001) @2775 I will certainly stick to Bernards solution of commenting out a line in the !Run file, as long as !PhotoDesk seemingly corrupts !Printers, although !Printers allows !PhotoDesk to load - if anyone is still following. Kind regards, Paul Sprangers
