I've written a program which changes the function of the keypad; I was trying to change the state of the NumLock LED with a CallBack, and discovered that a) the keyboard handler also changes it the same way, and b) the two CallBacks didn't always come in the same order - usually the keyboard handler got in first, but not always. I then added a delay of 0.1 sec with CallAfter, and everything seems OK. e----><----p | Stephen Burke | Internet: burke@vxdesy.desy.de H H 1 | Gruppe FH1T (Liverpool) | DECnet: vxdesy::burke (13313::burke) H H 11 | DESY, Notkestrasse 85 | BITNET: BURKE@DESYVAX or SB2@UKACRL HHHHH 1 | 2000 Hamburg 52 | JANET: sb2@uk.ac.rl.ib H H 1 | Germany | Phone: + 49 40 8998 2282 H H 11111 | HERA, the world's biggest electron microscope!
