After uploading and chossing a branding image for the sign-in dialog, the new image is shon by clients approx every other time the page is refreshed. Usually the first time a browser loads the sign-in page for Filr the original Novell- image is shown. A refresh switches to the branding image and another refresh switches back to the Novell image. And so on.
Just upgraded to 1.0.1, we didn't use branding images in the previous version. Background image stays after refresh. We seem to experience a vast improvement in access times in 1.0.1.
