My bookmark list takes up 2 columns in the dropdown that shows when I click on Bookmarks in the main menu. Sometimes when I click on Bookmarks I instead get either the "Bookmark Editor" or the "Create New Bookmark Folder" popup. I have not found a way to reproduce this reliably. But I think it has to do with the fact that the upper edge of the Bookmark dropdown window is not aligned UNDER the main menu items as the other main menu drop downs are but along the upper edge of the Konqueror window i.e. the Bookmark dropdown covers part of the main menu whereas none of the other main menu dropdowns do. Also, the time elapsed from clicking Bookmarks until the dropdown shows is a lot longer with 2 columns than 1 column.
