I have no idea what I did yesterday but suddenly my background is black instead of white and I can't pull down the drop downs from the top tabs anymore - if I double click and hold on File or Edit etc. the options appear but I can't click on any of them to select it. And when I'm trying to change the color of the text I can't get it to open the color options no matter what I do. What the heck happened and how do I fix this????
