Excel 2007 : I can"t paste / drag formula from one cell to another

I'm using excel 2007. Today I opened my excel to continue my work.
But when I copy/paste the cell with formula to another cell, it didn't copy the formula,
only the value. I tried dragging it down to the next row but only the value was pasted.
It didn't auto calculate. I check the calculations options, automatic is check-marked.

And not only the formula, it also won't copy the boarders, the styles, the fonts, etc.

I don't know what happened. Please help.

Hi,
are you using Skype, perhaps? There have been problems with the paste dialog caused by the Skype Click to Call plugin. If you are using Skype, upgrade to the latest version, because they fixed the bug.
