Comment 5 for bug 1827696

> The dropdown on the worker panel behaves as it should, the one on the ware panel refuses to open when clicking on it. Which peculiarity of dropdowns am I overlooking?

Check whether the ware panel is thinking, there might be a panel refresh in the way. Part fro that, it shouldn't disappear unless you move the mouse away or focus something else. We also can't rule out bugs - I recently fixed some in https://code.launchpad.net/~widelands-dev/widelands/toolbar-dropdown-menus
