Are events stackable? Or it works more like "signal()", e.g. in C? e.g. I have 2 different light sensor events set to watch for value higher than 42, yellow & blue. Let say both sensors read 45 at the same time, RCX returns only one event being (...) (21 years ago, 2-Jan-05, to lugnet.robotics.rcx.robolab, lugnet.robotics.rcx.nqc)

Elizabeth Mabrey, in her last post, referenced ROBOLAB 2.5.4B. I have just procured a copy from my Spectrum (distributor in Canada) but it is 2.5.4 (without the 'B'). Do I not have an up-to-date copy? ...or, is there a download for 'B' somewhere? (...) (21 years ago, 24-Dec-04, to lugnet.robotics.rcx.robolab)

Sorry, I think I need to clarify further... - This is in the "Investigator" section, NOT the regular program area. - after I click on the big "upload" arrow, I changed the dataset name to, e.g., "ds1", but there is no graph. - I click on the "upload (...)
