We are currently investigating an Outlook hang problem using WPA version 10 to analyse data captured with WPR. We see a 63-second solid bar in the UI Delays graph against the starting thread (also this is the UI thread) for the Outlook process. We've drilled into this a long way and we are pretty clear on the cause of the problem but we have a fundamental question that we need to answer.
Precisely what is being measured by the UI Delays graph?
Is this showing when there are periods where there are messages waiting to be serviced by Outlook's window message loop? Is it measuring something else?
Just to clarify, we don't want to know what to do when we see a 63-second solid bar but rather we want to know exactly what this means.
Thanks and regards...Paul
