do i need to make a backup of my skins before uninstalling version 6 of WindowBlinds, and then place them back in this folder ones WindowBlinds 7 is fully installed and activated???
I would think that Impulse is smart enough to sort through that.
However, it is a good idea to back up your skins, for events such as hard drive crashes or new computer purchases.
I always save my .wba's in a certain folder upon download, then I load them into WindowBlinds. I've upgraded or purchased new a couple of times in the last couple years and this practice has really helped!
