It appears that Excel could be starting with the worksheet in hidden mode and you can always 'unhide' immediately after you start the program. Allternatively, you could try this as a permanent solution:
1. Close all Office files or applications
2. Click start > Run and then type the following in the text box and press OK
Excel.exe /unregserver
3. Click start > Run and then type the following in the text box and press OK
Excel.exe /regserver
This should reset Excel back to it's default state.
Good luck!!
