Sequencer crashes on zooming out in image preview

I haven’t really used the sequencer before and am attempting to learn. I can import an avi file, switch to preview and play the file. I notice however that the file opens too large for the display window. I can zoom out, using my laptop mouse pad, up to a point, but at a certain stage in the zoom Blender stops working.

I think that it happens once the view matches the window size so that, if I continue the zoom a second too long, the crash occurs.

I’ve upgraded my version to Blender 2.49a today but the problem has continued.

Maybe a silly question.
You know that the size of the preview is connected to the Formatsettings in the Renderbuttons?
And you can use the 75%, 50%, 25% buttons as well if you want a smaller preview.
