From the Webmaster:

I would hope that most people have upgraded their web browsers and are not running Internet Explorer 6 (IE6) now, but there have been some people having trouble using Google Docs for the seating plan - this could possibly be attributed to using IE6 which Google no longer supports.

Upgrading is generally an easy process - not something to be too worried about.

We've not done it yet, but in a couple of weeks we will likely implement a check for IE6 when accessing this site. With that feature turned on, users with IE6 will see the following message...

Internet Explorer 6 is a very old browser and it is not supported in this site.

The following list contains some of the reasons why this browser it is not supported:

• It does not support the W3C standards.
• It is not compatible with CSS3.
• It has a very low score in Acid 3 test.
• It is insecure and slow.
• There are several movements against this browser: IE6: Do NOT want!, IE Death March, Dear IE6, Stop IE6.
• Google has officially stopped giving it support.
• And a funeral has even been celebrated.
