Look in your XLStart folder.

Report what you find.

I'm guessing that you have a file in that folder that's causing the trouble.

Hi,

I use Excel 2000 at work, and I recently started to get this issue,
when I first open any excel file, another workbook named "Book2" opens
automaticaly along with the first file. from then on, I can open
other files and no other books comes up. it only does it when I open a
first instance of excel. Do anyone have an idea of what could be
causing this?
