Green Upload 1/all, download 1/all buttons are missing


I have lost the following buttons that usually sit between the local and remote pane.
Upload 1 File,
Upload all Files,
Download 1 File and
Download all Files

I have just installed the program on vista (within the last week) and the buttons were in their usual position last time I used it. I have previously used Smart on my other XP machine.

I have rearranged via the View and Window Menu but cannot make these buttons appear. Does anyone know what they are called, where they are or how I can get them back? I am totally lost without them as they are the only function I know and use.

The connection to remote location is all OK and working. I have uploaded files a few days ago. Just dont understand how/why/where these buttons have gone.

Please help!
