We are on ChemStation A.9.01 with ChemStore B.02.01. We get the same information message if you stack plots and it is just that - an information message, so you don't wonder why your overlaid plot won't print a report. I would suspect that Agilent knew a report couldn't be generated, but hadn't fixed the bug, so just put the message in. I would guess later versions remove this - Agilent are unlikely to create a patch to correct it, since it isn't a critical defect.
We don't use the sequence summary report (we generated our own custom reports in ChemStore). However, having the column state the units from the config screen is logical - although you are generating a percent report, your internal procedures might require a different heading, so this gives the flexibility. Can you not just use "Percent" as the units for Sample Amount?
I don't recall instances where a run has not stopped acquiring. The only way I can think of this occuring is in your method, one of the HPLC components has a different run time to everything else, i.e. "No Limit", or a big number. The only other time the first run in a sequence gave problems (it acquired the run correctly, but the next run didn't start) was when we had external A/D boxes connected to the Analogue output and Remote connection. We traced this to the fact that the A/D box was turned off, so the HPLC didn't get a ready signal back after the run - if we turned them on again or disconnected all the cables, the sequence ran OK.
I'm not sure why you can't see the A and other non-C drives, unless you have some form of desktop lockdown that completely shields all drives. We have lockdown on our Windows NT desktops to prevent access to Explorer, etc., but we can still see all the drives from any Open/Save window, via the "Drives" dropdown.
Can't help with the last one - we don't have any 1050 autosamplers. However, I still find it odd, since the Offline session for an HPLC mirrors the Online session, as far as I know (unless there is some other configuration change that can be made so the offline session knows you have more than 21 vial tray.
