I doubt that very much. It likely runs but doesn't do what you expect. Examine the query, especially the sql view. Perhaps that view will point out the problem. Can also try switching from sql view to datasheet view. This view of an action query will show you how many records should be affected (not necessarily the actual effect), often showing empty records. If you get none, something is wrong with your query (criteria or links) based on your expectations. The foregoing assumes you have not disabled warnings at some point.
