Word Web App works for one member of my SkyDrive group but not the other two.

I am a member of a SkyDrive group that has three members.

For one of them, when they double click on a shared docx the Word Web App opens up like it should.

For the other two members, when they double click the browser times out.

I logged in as each member of the group on the same computer and tested the same shared file to get the above results?

Is there some permissions problem or anything that I can do to fix this?

Rob.
