How come when I switch back and forth with Alt-Esc among my sessions, when I end up in my Dos box I hear a little popping noise from my 8513 screen? This has happened pretty consistently since I got this PS/2-70 (last August). Is this indicative of a problem??

I, too, have noticed a small popping noise on some occasions, but not in the environment mentioned. It happens to me (sometimes) under DOS when the screen content undergoes a dramatic change, say from a full screen editor in graphics mode, switching back to the plain DOS prompt. This has occurred with EGA and VGA monitors. This has gone on for a couple of years without any apparent damage to anything (except my peace of mind). I would be very pleased to know what electronic/mechanical phenomenon is going on.

This has occurred with EGA and VGA monitors. The poping could be dust inside causing the static electricity to arc across when the screen "undergoes a dramatic change".. nothing to worry about.. although I would bet it does it when you turn the monitor off. -- Jack Computer Support Corportion Dallas,Texas Hudler UUCP: {texsun,texbell}!csccat!jack
