Internet Explorer Script Error
Internet Explorer may show a timeout warning like “Stop running this script?”
when optimizing large routes. This is a known browser limitation — and it’s safe to continue.
Quick fix: When the warning appears, click No to allow the process to finish.
For better performance, use Chrome, Firefox, or Edge.
Why it happens🔗
Internet Explorer has a built-in script timeout warning. When the number of stops is large
(often 20+ stops), route calculations and UI updates can take longer than IE expects,
which triggers the popup.
What to do🔗
- When IE asks “Stop running this script?”, click No.
- If you optimize large routes regularly, switch to a modern browser.
- Recommended: Chrome, Firefox, Edge (faster + more stable for large datasets).
Want faster route optimization?🔗
TrackRoad works best on modern browsers. Chrome, Firefox, and Edge handle large routes more smoothly and avoid IE timeout warnings.
