>Cyril, VFP will not update the screen if it is in a very tight/fast loop busy with something else. You need to create a slight pause after you update your thermometer to let VFP update the screen eg INKEY(0.01,"H") will probably do it. Also read up on DOEVENTS.

OK thanks, I'll give INKEY(0.01,"H") a try.
