OK. I can now see the CRIDs but to do so I found that I had to enable "Debug mode" (from thread link in #4 post above) as well. Thanks for the help.
To stop this thread from becoming too long and complicated to follow do you guys think I should now close it and, if the problem returns, start a new thread including full details and "Series CRIDs"? The new thread would then be easier to follow?
