I use Outlook 2010 and Windows 7 operating system. Whenever I need to attach an Excel File, I click on attachment attachment and then selected the Excel workbook by clicking on it . Whenever I do this the Excel workbook opens up. I then need to go back to my message and then click on Insert to attach my workbook. It appears that a setting needs to be made so that when attaching the workbook, it is not so sensitive and it will allow me to click on iinsert after click on the workbook I want to select. I never had this problem when using XP.

Your assistance in this regard will be most appreciated
