PS: you can get the same function that the green button used to have (that is, to resize your window), by keeping pressed the 'alt' button when you click it. This seems to work for me, but I would much rather prefer for a software update (that will remove this glitch.) :-) You may then resize your spreadsheet, and then change back to your default resolution. That will force excel to resize the sheet, and you will see again the resize box at the corner. However, your answer did provide for a clumsy solution! :-) Charles, try to change your screen resolution. 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! :-)
