Thanks for catching the typo. Yes. You fixed it correctly. I have Windows7 64 bit. I tried to reproduce your situation here and couldn't. You have another option. There is a way to add a menu option to do the same thing as the Shell Extenson which isn't working. Or I can continue to try tacking down the problem.
Here's a link to a page with the instructions if you want to use this alternative. I used to use it myself when I ran XP and it worked. The only issue might be if you had a security program which used script blocking , or had the file assocation changed so that scripts would open in Notepad.
