This site has graphical scroll buttons that scroll the text when mouse hovers on
them, does not work. Just go to BIO, NEWS, CONTACT, etc. This while site seems
to use these up and down graphics, which when u put the mouse over them, the
text scrolls. It works fine in IE but will do nothing in mozilla, making reading
the entire text impossible.

Reproducible: Always

Steps to Reproduce:
1. Go to site
2. Pick BIO for example
3. Try to scroll text, will not do anything

Actual Results:  
Cannot scroll text

Expected Results:  
Make this feature usable.

Using Pinball theme, other than this, nothing different than Mozilla as
downloaded. Installed Java and flash.

Page assumes either document.layers or document.all, which Mozilla does not
have.  --> TE

(The site is in english but comments in the JS code are in italian,
 so assigning to TE/Italian)

This is the function that needs to be fixed (could be more though):


function tmt_scrollLayerBy(bersaglio, dx, dy, vel) {
    if (document.layers) {
        turi = document.layers[bersaglio];
        var cl = turi.clip.left;
        var ct = turi.clip.top;
        var cr = turi.clip.right;
        var cb = turi.clip.bottom;
        var l = turi.left;
        var t = turi.top;
        turi.clip.left = cl + dx;
        turi.clip.top = ct + dy;
        turi.clip.right = cr + dx;
        turi.clip.bottom = cb + dy;
        turi.top = t - dy;
        turi.left = l - dx;
    } else {
        if (document.all) {
            turi = eval("document.all." + bersaglio + ".style");
            if (turi.clip) {
                var clipv = turi.clip.split("rect(")[1].split(")")[0].split("px");
                var ct = Number(clipv[0]);
                var cr = Number(clipv[1]);
                var cb = Number(clipv[2]);
                var cl = Number(clipv[3]);
                var l = turi.pixelLeft;
                var t = turi.pixelTop;
            }
            ncl = cl + dx;
            nct = ct + dy;
            ncr = cr + dx;
            ncb = cb + dy;
            turi.pixelTop = t - dy;
            turi.pixelLeft = l - dx;
            eval("turi.clip = 'rect(' + nct + ' ' +  ncr + ' ' + ncb + ' ' + ncl
+')'");
        }
    }
    tmt_scrollalo = setTimeout("tmt_scrollLayerBy('" + bersaglio + "'," + dx +
"," + dy + "," + vel + ")", vel);
}
