Possible repro steps:
1. Image Trace (Low fidelity - 10 colors)
2. Expand
3. Preview many different color libraries through Recolor > Color Library
4. Recolor > Color Library > Color Books > HKS Z
Since it happed after I had previewed many different Recolor presets, there may have been a built up cache of swatches or something. I clicked "OK" approx. 125 times before the dialogue box went away (I counted the second time it happened). It would be cool to have a "Cancel" or "Undo" button for this warning. It takes about a minute of clicking to close out of the dialogue box.
This happened to me as well.
