Gmail hangs when opening in Chrome

Hangs in Chrome, fine in Firefox.

To fix:

Open Chrome (if not already open)
Close the offending Gmail tab.
Go to History (ctrl-h)
Select Clear Browsing History
from the profferrd list select:

• Browsing history
• Downloaded files.
• Cached images and files
• Hosted app data

Do not clear cookies, password etc.. Cookies are not at the root of this problem.

Your Gmail should then work OK.
