How did you get that on 7?
One odd idea is to configure OE to not use Word. Here's how.
"Select Tools | Options from the menu in Outlook.
Click on the Mail Format tab.
Make sure the Use Microsoft Office Word to edit e-mail messages checkbox is NOT selected."
I have windows 7. I am getting a popup on outlook express that tells me I am not allowed to "FORWARD" anything unless I upgrade Word. I have word 2010. Has anybody had this problem before. Help!
