You need to open Impulse, click on the menu icon in the top left corner, check "Show PreRelease Versions".  You should then see Windowblinds 7 - that's what you're after.

I think I owe you an apology - I think I misread your initial post.  When you said you were a subscriber, I interpreted that to mean you are an Object Desktop subscriber.  Looking at your screenshot and back at your post, I think what you were saying is that you have just the Windowblinds, not the Object Desktop.  Is that correct?

The difference is that the beta versions are only available to Object Desktop subscribers and the Windowblinds 7 is still a beta, so you'd need to have an ODesktop subscription to get it.  Here's a thread that goes into it, a little dated but I believe still applicable:

Sorry again about the confusion.  And of course, if I've missed the boat yet again, anyone's free to correct me.

Yet again, Sorry for the very late response. I have various applications regarding WB. I also have; Icon, Cursor and Sound. All were purchased seperately at various times. If I am understanding this correctly, I am not eligable for this "free upgrade" as I am NOT a O.D subscriber.

I had purchased WB over a year ago and was my first purchase. Then the rest of the apps followed. I have no problem purchasing O.D.  I dunno...I guess I (purchased sperate apps) did it that way because I was nieve or I wasn't thinking correctly and maybe I only wanted certain apps.  Anyways, the bottom line is that if I don't quailify then I will purchase whatever I need to continue using the software of choice. I mean, if I can spend over 3K on my gaming rig then why not?

*EDIT*

I just seen something. Could I upgrade to O.D or the ultimate for having some of the listed apps? LINK

If you haven't chosen between Object Desktop and Object Desktop Ultimate you might want to have a look at this thread, it might affect your choice:

"On December 2, 2009, Object Desktop and Object Desktop Ultimate will be merged into Object Desktop. Users with Object Desktop Ultimate will get a full year added to their account (so now is the ideal time to pick up Object Desktop Ultimate)."

People rarely post in the support forums to tell you how great a product works. It is still in beta so it does still have a few bugs to work out but for the vast majority it is working fine.
