Error in ISQL v 4.00

Hello informix mailing list. I would like to hear if anybody has expirienced the following error in Informix-SQL ver.4. In a form with multiple screens and the same key field in all the screens it is only possible to query on it in the first screen, even though all the fields are refering to the same field tag. It is very easy to test, because the the error is present in the demonstration program 'sample'. I am running Informix-SQL and -SE ver. 4.00.UD2 on an Altos 5000 with SCO-Unix Sys V 3.2.1a. __________________________________________________________________________ ___ ___ _ _ _ _ ____ _ ___ _ _ _____ _ _ _ | \\ | \\ / \\ / \\ |\\ | | / \\ | \\ |\\ /| /\\ | | | / |__/ |__/ | | \\_/ | \\ | |__ | | |__/ | \\/ | / \\ | | |/ | |\\ | | | | \\| | | | |\\ | | |____| | | |\\ | | \\ \\_/ | | \\ | \\_/ | \\ | | | | | | | \\_ __________________________________________________________________________ Niels Berner, Pro Informatik. <berner@proinf.dk> Produktionsvej 2, DK-2600 GLOSTRUP, DENMARK.
