I periodically get this error pop up. I'm never quite sure what caused it because it happens with multiple SMATH files.

If I click on continue, things seem to progress as normal giving the correct answer.
Is there any guidance on the various conditions that cause this? The text is not always the same. If I click on Details, I'm not smart enough to understand the diagnosis. I don't recall it happening before I recently updated SMATH to SMATH Solver.
Thanks,
Reg
