I'm not the most savvy Excel user so I'm not really sure how to explain this so here goes.
I'm creating a pretty basic document with some calculation and text in different cells. Suddenly I click on a cell and attempt to write some text and it will only except one letter in the cell. In other words, if I try to write the word "Cell" I type the "C" and then when I hit "e" it just overwrites the "C." ....and so on. Whatever letter I hit last is the letter in the cell. I can to to any other cell in the document and it will do the same thing. I can even open a new sheet in that document and same thing. I can go to a previous cell and cut and paste a word into a the misbehaving cells. Progress has come to a complete hault! Can anyone help!
