4GL TAB order

Using 4GL version 6.x with Informix SE on a Sun machine recently upgraded from SunOS to Solaris 2.6. Suddenly we can't seem to navigate using the tab keys or the arrow keys in the any of our 4GL forms. Anybody have any idea what this could be? thanks, Maria -------------------------------------------------------- Maria L.
