Hi

can you try this for me at the command line in cad type
FILEDIA and enter a value of 1 this should fix the New, Open and Save dialog problem.
If that didn't work try this in cad
1: Enter CUI command;
2: Expand Customizations in All CUI Files;
3: Expand Shortcut Menus->Default Menu in the tree-view;
Than you can add any desired function in right-click menu.
