For Excel 2003 user's....
All button edit in Excel ( the Cut, Copy & Paste icons) are greyed out...
Kalau jadi macam ni biasanya in Excel still do Ctrl C & Ctrl V guna keyboard, but can't get Paste Special...
Kalau right-click the three are greyed out there as well...
Solution :
Go to Tools, Customize, Toolbars, Reset, Ok/Close......
