In fact, it is not inexplicably wonderful. At most, operators like to drag the menu, and use CTRL X;
Sometimes the user doesn't know where to drag it; sometimes or put it hide, if it is also very tired in many menus, it is not necessarily found;
1) Note the menu, right click, select [Show Hide Project];
If the operator is only [hidden], most cases can be solved;
2) If you haven't found it yet, then click the menu, right click, select [Reset Use file];
This method should make the menu you want;
If you don't do it again (usually not), use the third method;
3) Run regedit; hkey_current_user-> Software-> IFS-> Centura Client-> Personal
Remove all subplices under this project;
