I developed a website with vs2005 c# which uses a treeview for navigation.
I selected the option show lines (solid) there. If the menu is collapsed the layout is very fine (with IE7 or Firefox). If you click on some knode to open it you see the solid lines as broken lines (like dashed). You can try this page: http://eu1.at/oris (with IE7 or Firefox) to see this layout problem.
Is there any solution for this problem? Thanks in advance
