Version: (using KDE KDE 3.3.2) Installed from: Gentoo Packages Open a PDF in kghostview. ctrl-shift-f to get to fullscreen. ctrl-m to show the menu. Press 's' for example (other shortcuts have the same effect). Now clicking the menu items goes to the next page instead of opening the menu. Hiding and showing the menu again fixes this.
Works just fine in Okular.
