We recently acquired an UPLC-MS system with an OpenLab CDS software. Sometimes, just after the beginning of a sequence a message appears in the "run queue" window. This message is : "Active Queue: data system NOT accepting sequences (the current methos has been modified. Save or discard the changes". The sequence still runs and we succeed in getting our results. So, we were wondering : what does it mean and why do we have this message?
Moreover, we observed that when a method is loaded, the software always says that we changed the method even if it is not the case and ask us if we want the changes to be saved. Do you know why?
