WORDWRAP gives Segmentation Violation

Hi Problem : Upgraded everything: Solaris 2.6, Informix 4GL ... Latest version Programmed worked fine before, but now it gives a segmentation fault when editing a "formonly". If I remove the Attribute "WORDWRAP" from the .per file, it workes fine except for the wordwrapping function. Are there someone out there that have any idea ab how to solve this. I am very,very new to this 4GL stuff !
