Version: (using KDE KDE 3.5.5) Installed from: Mandriva RPMs Compiler: gcc-4.1.2 OS: Linux on http://www.agencebretagnepresse.com/, konqueror display the same javascript menu as firefox does. However, this menu is reapeated at bottom right of the page... at coordinates 30.000x30.000, which make the page very very large.
Confirmed this behaviour on KDE 3.5.5 / Kubuntu 6.10. Appears as though the site is using this "off page" area to store the menu dropdowns and then repositioning them into place on mouseover (note how they "vanish" from the off-page area when mouseovered).
Still here in Kde 4.0.3/Kubuntu. Would have thought they'd have updated the site by now ;)
Confirmed the problem on konqueror 4 (trunk).
No longer reproducible, may be the site has been updated. (KDE 4.11.4)
