Please search in start menu 'View all problem reports', find Windows Explorer crash with time when crash happened, then zip and upload the 4 files that show up under "files that help describe the problem". If there aren't any, copy crash details and post them here.

Hmm, please explain what item exactly you click.
I'm clicking any application in the Start Apps folder on the start menu. In this case i clicked mail.
Well a reinstall seems to have fixed it.
