Thanks for the replys, I tried what foo_bar_foo suggested (deleting the files and have them automaticly rebuild) and that seemed to work... for a while. After I rebooted, the menus were ok but when I made my change (added a program) to the menu, I lost the different icons: All the folders and subfolders had the same icon - the blue folder (like the one you see in konqueror). So why do I lose my icons when I save with menudrake ?
Another question: it seem that a subfolder will only appear when there's a least one program within it, right ? But sometimes, there is a program within a subfolder but it won't show. Any ideas ?
