We've tried to make our application as cross browser compliant as we can. However some browsers have major security issues and are inherently unstable. Internet Explorer (IE) is one such browser and we do not recommend it. We also, like gmail, do not support earlier versions such as those before IE9.0.
If you are using IE on your computer we would recommend downloading any of the following browsers as a replacement. They are all FREE.
Chrome is perhaps the fastest with least processor load, and then Firefox. Always stay up to date with the latest stable browser releases to ensure the best experience too.
