Your best bet is to post this request on the CEEO web site. Someone there will surely answer. AFAIK, it's intended to be supported in all environments. (18 years ago, 28-Feb-07, to lugnet.robotics)

Does anyone know what versions of Robolab support the RCX Control Pad? I have tried it with RoboLab 2.5, 2.54B & C, and 2.9. In all cases Robolab hangs or I get VI execution errors. I want to use this for an outreach project where school chirdren (...) (18 years ago, 28-Feb-07, to lugnet.robotics)

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.
