For the last few days, when I open a new tab in Chrome (on Windows 7), it no longer shows any arrow or other link to get to my web apps. It is also white, instead of using my theme as previously, with a huge GOOGLE search box - but the search box does not accept any text :( It still shows thumbnails of 8 frequent links, but the links do not work; if I click on one, it goes grey (and shows a closing cross), but does not take me to the web site.
The same behaviour is on several computers. Any ideas? Can I get the old, functioning version back?
