I have that plug-ins installed also because my blog has ever been trapped in a frame before >:) but i have no idea of what will appear on someone else's frame when she or he does it to my blog, have u ever tested it?

and i thought that its plug-ins was made by FreeMoby?

the script does the following: if your blog is in a frame, the page automatically reloads itself and sets itself as the top document.

and FreeMoby made a very similar script a few days ago indeed. i didn't know. ;)
