Stardock has pushed the final release date of WindowBlinds 4 back one week so that it can go through final compatibility testing. The first release candidate should be available in the next day or so for those users who have Object Desktop.If you want WindowBlinds 4 right now, you can get Object Desktop.
Also, the WindowBlinds 4 Media Guide has been completed. Now you can check out everything that's new in WindowBlinds 4.

(Hint, hint...)
Every one that is complaining about the changed date should go out and get a life there are other things to do then edit your desktop. I too am waiting for the update but it will not happen faster with you checking the site a thousand times a day. Go to a party a bar or just go to your friends house and have fun. I know a lot of people have fun by creating new skins and I thank you but in the mean time take a break and relax the world will still be spinning tomarrow with or without the release of WB 4. Try to relax a little.
