i encountered a strange behaviour this week:

starting of with Operation ItemSearch it found the items i was looking for.
i clicked on the item i wanted (ItemLookup) and got an error message (Sorry ...)
went back to the initial page, clicked the item again (The ItemId is invalid)
went back again to the initial page, clicked once more and voila there it was. seems like AWS has gone very unstable, no wonder i get these emails 'you did not generate any earnings during the month of april'.

i think i must go back to the html item page versions that we all did manually in 2001 or so.
