Excel opens twice
 

For some reason Excel 2007 has started opening two windows, one with the file
I want to open and one blank (no worksheet) when I click to opne any Excel
file. I have run repair which hasn't stopped the occurance.

Ocassionally, Excel menus become unresponsive and I'll have minamize and
then maxamize in before the menus are responsive. I don't know if this issue
is conneted to the double opening of Excel or a seperate issue.

I am running Office 2007 Pro in Mindows Vista Buisness a Dell Inspiron 8600
with two gigs of ram, 7200 rpm hd, 1.7 ghz mobile chip.

Thanks
