Vista - Photo gallery opens all the pictures in the folder on left click.

Ok I feel stupid for this. Here's what I did. I inserted my camera's SD
card into my computer and instead of importing like I should, I just did a
cut and paste. I was going to delete all the photos anyway. Bad move, now
when I left click on an individual pix the whole folder contents are
displayed. I can however right click and then right click again on preview
to see the individual picture. I changed the file association to Office
picture manager and it works fine. Is there any other way to fix this
besides changing picture file program association? The SD card is now blank
and undo is not available. Vista bugs you gotta love 'em
