A problem with wordwrap

Hi We are using informix 4.00.UD2 and sco unix 3.2. We are having problems with forms which contains wordwrap fields and we want to know if it's a known bug and if it is also corrected in 4.10. Suppose an application that during an input statement the user presses a key and it pops up a window which let him select a list of possible values according to some selection criteria (another input statement to enter this selection criteria). If the field in the first input is wordwrap, after the help window is closed any key pressed by the user (except arrows keys, tab, enter) generates core dump. If it helps, the trace of the process is the following: _next_line(0x7ffff8f8, 0x7ffff8f4, 0x4279ac, 0x7ffff8fc, 0x7ffff91c, 0x7ffff904, 0x7ffff900, 0x0) from _ww_put_rest+0x1f1 _ww_put_rest(0x4279a8, 0x9cb78, 0x4279f8, 0x0, 0x2000) from _chared+0x4bf _chared(0x4279a8, 0x0, 0x426ad4, 0x50, 0xc002, 0x4010ac) from _effin+0x92 _effin(0x4279a8, 0x72, 0x0, 0x426710, 0x0, 0x7ffffa26, 0x0, 0x426ad4, 0x50) from _efget+0x226 _efget(0x426710, 0x426ad4, 0x4013c8, 0x2000) from _effget+0xa5 _effget(0xf, 0x0, 0x4013c8, 0x0, 0xffffffff) from _inputrow+0x209 _inputrow(0x16, 0x40125c, 0x0, 0x4011a4, 0x4010ac) from _finput+0x19c _finput(0x16, 0x40125c, 0x4011a4, 0x1, 0x4010ac, 0x401b14) from input_operacion+0x511b input_operacion(0x1) from carga_operacion+0x97 carga_operacion(0x0) from main+0x78b main(0xf, 0x7ffffd44, 0x7ffffd84) from _start+0x3b Thanx in advance =============================================================================== Francisco Javier Lopez | internet: javier@lucas.mrec.ar United Nations Development Programme | uucp: ...!uunet!atina!lucas!javier Reconquista 1088 1er.
