Download the Painted Skies Theme for Windows

Beware of the unseen change this particular themepack makes to your screensaver settings (in Windows 7 at least). It will change the screensaver to "Blank" and set it to kick in at 5 minutes. Resulting in your computer's display suddenly going blank every 5 minutes of non-input activity.

You can verify this before loading this themepack by going to Control Panel\All Control Panel Items\Personalization: scroll to the bottom and check that your screensaver is set to "None." Then load this themepack, and return to the screensaver menu: it's suddenly set to go Blank after 5 minutes.

Very upsetting and seemingly unnecessary -- no other themepack I've tried makes this hidden system change. And very hard to track down the source of the sudden blanking behavior. If you google forum posts on such a problem, you'll encounter a myriad of suggested solutions involving everything from disabling your display adaptor to tearing open your computer and re-seating every plug and card, to replacing your 'failing' power supply!

Fortunately I found the correct solution after some serious searching (after wading through the many similar posts where people are experiencing the blanking problem but at sporadic times, and where they report simultaneous freezing/lockup problems).

I don't see where one can comment on individual themepacks on MS' download page, so am posting this here to hopefully save others the same confounded frustration and wild goose chases I experienced. If the creator of this themepack is reading, seriously dude, change that default setting in it!
