OS:Windows 7
Default browser: Google Chome
Mainly used browser: Google Chome Canary

I like to save web addresses by dragging the URL top the desktop. And usually they show up as an icon on the desktop, and the icon picture is a picture of what programme the icons up with, in this case Google Chrome. So usually there is a Google Chrome icon for these icons. I'm not exactly sure what caused the problem. But recently I installed the Google Chrome beta (Google Chrome Canary).
Here is a screenshot showing the bookmarked websites that have a white box on them instead of the Chrome logo.

What can I do to solve this problem?
Thanks in advance,
Thomas.
