I updated my WindowBlinds from 6 to 7 a couple of days ago and it was fine, apart from not being as easy to use as v6.
Today when I switched my PC on the Windows came up in Classic theme, which is awful. I normally have it set to Random so I get a different theme every day. The random option won't work and no matter what theme I select I get Windows XP.
I've rebooted and now I can change theme but when I do the screen changes resolution.
I've removed v7 and I'm going back to v6 which is easier to use and better layed out.
