Missing views dropdown on list view web part.

Question

I asked this before, and it got moved to "admin" with no replies.  I really need to know this.  I think it may be appropriate for design and customization, because I think that's what the solution may require.  It doesn't appear to be an "admin" issue.
Any help will be gratefully received.  I am very frustrated by this.  The  "View:" dropdown list on the right side of the list view web part for my document libraries is not available.  The truly weird thing is that in a few cases, it is there, but I can't tell any difference between those web parts or DLs and the ones without the views drop-down.  I have defined several public views for each document library. There are no "closed" web parts on the page (which was one suggestion I got).
I can't figure out why the views menu sometimes appears and sometimes does not, when there appears to be no way to control it. Can anyone enlighten me or suggest how I can make it appear?  My users are threatening to demand a separate web part for each view (there are hundreds).  I may have trouble using SPD on the client's site.

That works if the Web Part was Closed, but does not help if the user deleted the Web Part. 
After some digging around in SharePoint Designer and in SharePoint itself, I have a solution for restoring the View dropdown after the out-of-the-box List View Web Part has been deleted.  This solution can be accomplished without SharePoint Designer if you are working with a library, but to clean out the views from a list, you will need SharePoint Designer.  I am doing this in MOSS 2007 SP1, but it should work for WSS 3.0 as well.
For this example, I am using a document library called Public Documents and my View is allitems.aspx, but this should work for any list or library. 
Here are the steps for bringing back the View dropdown:
1.       Navigate to the list or library that is missing the View dropdown
2.       Go to Site Actions > Edit Page > Add a Web Part .  In the Lists and Libraries section, check the box next to the Public Documents library and click the Add button.
3.       Within the new Web Part, go to edit > Modify Shared Web Part and change the Toolbar Type to “Full Toolbar”.  Click the OK button.
4.       Click the link to Exit Edit Mode and you should have the Full Toolbar for the list/library displayed, but it is still missing the View dropdown menu. 
5.       Go to Settings > Create View .
6.       Choose Standard View .
7.       Name the view, check the “Make this the default view” box, select the columns to include, and click the OK button.
8.       Voila, the View dropdown menu is back on the site.
9.       To completely clean it up, for a list, open in SharePoint Designer and delete the allitems.aspx view from the Forms folder.  For a library, you can go to the Actions menu and select Open with Windows Explorer .  Open the Forms folder (you may need to show hidden files to see this folder) and delete the allitems.aspx view.  If you do not have access to SharePoint Designer and you are working in a list, you will need to delete the link on the Quick Launch and add again to point to your new view name.
10.   If the View you deleted was the default for the list or library, it may remove the link from the Quick Launch.  It can be added again by going to View All Site Content , selecting the appropriate list or library, going into its Settings menu, and modifying the Title, description and navigation settings to show on the Quick Launch.
