See screenshots below.
Sometimes after a couple of minutes I get a message on the page that I should clear my browser's cache.
This happens in Chrome and Firefox, but I haven't encountered the problem in Explorer.
The OS is Windows 7. Chrome is up-to-date.
Temporary remedies that I have found:
- Clearing the cache sometimes helps for a while, but the problem comes back.
- Going the Chrome->Tools->Task manager, and closing the Google Drive task helps, but the problem comes back.
Re-installing Chrome didn't help.
Found these screenshots in the google forum (not mine):
