Hi, I know that it is like 2 years back. I need to fix this now in order for
me to be able to use 2 screens to speed up my work.

My problem with regards to your instruction below:-

"Go to explorer, choose tools, then folder options. Click the File Types
tab. Scroll down to the XLS extension. Click the Advanced button. Choose
"open", then click the edit button"

What do you mean by 'explorer'? Internet explorer? I couldn't find anything
said above. Please advice.
