General - Right-click BlogThis and IE6
So you just had to download Internet Explorer 6 (or buy a new computer that came with it), and now you find that the right-click version of BlogThis gives you a script error everywhere except at www.blogger.com, and you would like to fix it. Marcus has your fix, until Ev. gets around to making the incredibly simple change in the Blogger version of the script. [Additional discussion of the problem in Discuss]
Upgraded to Pro and need to upgrade your BlogThis? If you are using the IE6 fix, just open the file on your computer, and change www.blogger.com to pro.blogger.com or if you are still using the original, run regedit, search for blogthis, and change the (Default) key's value from www to pro.
