I use Fireworks a lot and one thing I am constantly doing is dragging items in the layers menu in order to re arrange their order from top to bottom. Today, for some reason, I am unable to drag. Instead, my only option is to right click on the item over in the main area of the png and then go to Arrange > step backward (or forward). I don't know what is causing me to not have the simple drag and drop option but it is driving me crazy. Any ideas?
