Well, you are right, the frames are my biggest problem now

When constructing the site I didn't know that, and now it's a lot of work to erase this frame. Well, at the time I don't even have an idea how I should delete them. The pages are shown in 2 different frames - some are big and some small. And now there is no navigation menu on these sites.
I fixed the 'entrance' problem a little bit. I looked into the HTTP_REFERAL value and if it wasn't www.paul-simon.info where the visitor came from I've send him back to the main page, and loaded the page he searched for into the iframe. (So everything looked perfect, he got the info he searched for and also was on the mainframe page)
It worked with Internet Explorer and Mozilla, but doesn't work on some other plattforms (Mac with IE, or Linux with Opra).
