We recently began to use a Unicode SAP system. I realise that the GuiXT scripts consequently have to be saved in UTF8 format, which we have done. But one of the pushbuttons that calls an InputScript still doesn't work. What could be the reason?

A possible reason is that you use special characters, e.g. German Umlaut äöü or French accents é î ç etc in the file name that you specify with "process=". Please use a different file name consisting of ASCII characters only.
