* Tests if clicking the "Make New Folder" button in a SHBrowseForFolder

*
* Here follows a description of what happens on W2K,Vista, W2K8, W7:
* When the "Make New Folder" button is clicked a new folder is created and
* inserted into the tree. The folder is given a default name that depends on
* the locale (e.g. "New Folder"). The folder name is selected and the dialog
* waits for the user to type in a new name. The folder is renamed when the user
* types in a name and presses enter.
*
* Note that XP and W2K3 do not select the folder name or wait for the user
* to type in a new folder name. This behavior is considered broken as most
* users would like to give the folder a name after creating it. The fact that
* it originally waited for the user to type in a new folder name(W2K), and then
* again was changed back wait for the new folder name(Vista, W2K8, W7),
* indicates that MS also believes that it was broken in XP and W2K3.
