Here is a small temporary fix as emulated from the Nucleus site (one of their answers is flawed and their own code has bugs, oh well)
Create a new file on the root of your blog called rightclick.php and put the following in there (replace open(‘http://… with your own servername):
Now create another file on your desktop called wordpress.reg and put the following in there (again replace the varibles please):
[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\MenuExt\Post To &WP : Mindful Musings]
Now double click on the wordpress.reg file to add the information to the registry and the right click in IE should work at that point.
