I'm afraid to ask what version of IE you use, since I succeed to drag the bookmarklet in IE9 :) I've found the following workaround for IE users:
1. Right-click on the link
2. Select "Add to Favorites"
3. Click "Yes" on security warning
4. Select "Favorites Bar" from the "create in" dropdown
5. Click "Add" button
Great job tho. I like the idea and I'll be using it when I get home.
