Attachment Uploader misses a 'browse' button.
The following steps are part of the instructions to upload an attachment:
1. Click on the gold image icon. This opens up the Wiki Attachment Browser.
2. Click on 'New Attachment'. This opens a 2nd popup.
3. Then you need to Click in 'Upload File'. This opens a 3rd popup to select a file from your computer.
On step 3 there should be a 'browse' button like on VW3. Its not logical that an empty field needs to be clicked.
