Zoho Spreadsheets Crashing

Zoho Spreadsheets Crashing

We are using Internet Explorer Version 8 on both a lap top and a desktop computer. These were the two that crashed when we  tried to make changes to the Zoho Spreadsheet. We updated the browser a few weeks ago thinking this might be the issue. But it is still crashing.

What do we do to prevent this from happening?  Thank you!
