Hi,
I hope somebody can help me with this. I created a new spreadsheet this morning and saved it as normal. Now when I open it, I cannot type anything into it and the mouse cannot click on anything useful. As an experiment, I also opened a new excel document and I have the same thing. It also seems that Word is the same - open a new document and keyboard will not type/mouse cannot click on anything.
Using the network, I opened this mornings spreadsheet on another pc and I was able to work on it with no problem.
i´m by no means an expert with excel, but the only thing i can think of is:have you tried opening the spreadsheet on the machine you created it on, have you locked the spreadsheet in any way (set a password)
