When a customer was changed to/from a tax-exempt customer, the hidden TaxPercent field was correctly updated to 0 but the live pricing preview was not re-run, so the display showed a stale total with tax applied. Selecting a tax-exempt customer now immediately triggers a recalc so the on-screen total matches the amount that will be saved. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
