But when you exit full screen mode, the excel window gets so big, you can't see the r esize box at the bottom right corner (and thus, you are unable to resize your window). Actually, when you are in full screen mode, you can see the different excel sheets and all. GeOS3, its not a problem with full screen mode. I face the same problem with Charles, and its quite frustrating to be honest. Edit: GeOS, i read your message really fast, and I failed to see that you indeed provided for the solution! My bad! :-)
