Yes, if I check some runs to compare then click the compare button, followed by selecting the query radio button and clicking GO, I will get an error dialog (see the attached errorMeassage.rft file). If I click okay on the error dialog and reload the same URL most of the time it will work. This is the most reproducable sequence but it doesn't always happen. When performing the above sequence, on the same runs, it will happen, maybe, 5 out ten times. It seems to happen less often with smaller runs.

Thanks,
Bill
