Just to expand on that... I have it open right now, so I am doing it as I type... what you have to do is:
a) With the mouse just click and drag the title bar (where it says "Turbo Lister") down just a bit. That moves the entire window off the top of the screen
b) Now, put the mouse over the top edge of the window until it turns into a double-headed arrow, then click and drag that top edge downwards about 20 or 25mm.
c) Finally, repeat the first step by clicking on the title bar and dragging the entire window up to teh top of the screen again.
The Cancel and Save buttons should now show - if not, repeat the steps until the window is resized short enough.
