Thanks. I thought setting maxlight before the 'if' statement would be enough, but moving it closer to the front (before the 'while' statement') did the trick. The bit after the while loop still gives me pain though. I've changed it a bit to be able (...) (19 years ago, 25-Feb-07, to lugnet.robotics)

(...) Looks like you're setting maxlight = SENSOR_2, then testing if (SENSOR_2 > maxlight), which will rarely (if ever) be true, because the value of SENSOR_2 is unlikely to change in such a short time. I think the first maxlight = SENSOR_2 (...) (19 years ago, 25-Feb-07, to lugnet.robotics)

I'm very glad to know you got it working again. Incidently, the '1.02' I was talking about isn't the version number on NXT-G itself, but on the USB driver it uses. If you haven't updated that, you can still occassionally get locking into 'clicking (...) (19 years ago, 25-Feb-07, to lugnet.robotics.nxt)
