I just updated to the last version of WordPress and it seems to have changed something in my CSS, although I can't understand why. WP 3.0.5 is supposed to be about enhanced security, and CSS trouble are not a known issue, are they?
here is the gradient :
As you can see, it was affixed to the body element and used to make the page greyish at the top and bottom, and white at the center. It is still working, except now the gradient applies on the window screen instead of the whole page and then repeats itself vertically.
And the whole thing began just after upgrading
