When I am working with Excel files with ReportBuilder queries, but I am offline on a train or a plane, I am inundated with ReportBuilder errors. this is particularly pronounced when I am pasting an Excel worksheet object into Word docs, and absolutely prevents further work when I click open the Excel worksheet object in Word. the error popup (which I can add when I connect from my PC but I don't have it at hand now) pops up again and again and again every time I close it.
