Cannot clone views

in CW 2 Site-Admins Helping Site-Admins

Hello again,

My TimeBank would like to display the user's address on their profile. I see that I can modify the view user_prof_additional to show that. But I've also read that I should create my own views to prevent changes being overwritten (which happened recently, apparently). The UI offers a Clone option on views, however either I'm doing something wrong or there's a bug. 

Here's what happens. I can click on Clone on a view, then it prompts me to put a name for the view, so I put something like user_prof_additional_clone. Then I click Save to save the new view. The site then shows a page that says:

The view user_prof_additional_clone has been saved.
Page not found
The requested page could not be found.

When I go to the views page, /admin/build/views, user_prof_additional_clone isn't listed, so I can never use it.

Can you let me know what I'm doing wrong?
