Real mail address is igoddard > at nildram co uk I found the problem, as Ian pointed out it was the visual bell. Here is what I did to fix it so when the bell should sound it won't go into reverse and stay there. $ infocmp -L > xterm.terminfo Modified the generated xterm.terminfo file and changed flash_screen=\\E[?5h$<100/>\\E[?5l to flash_screen=^G $ tic -s xterm.terminfo This put my modified terminfo xterm in ~/.terminfo. Now I get the bell sound and the screen doesn't go into reverse. Does anyone know why the 4GL programs are using flash_screen= instead of bell= in the xterm terminfo file.
