Workflow Log - No proceedings found

Hi Experts,

I had developed a simple workflow scenario (SWDD) just to send a mail to inbox which contains only 2 items (in SBWP):

Accept or Reject.

I had created the step for User decison & steps for Approval and Reject only.

Workflow is error free and activated.

When i see the Graphical workflow log, the green line stopped at the decision step to approve or reject.

After this, it has to send a mail to SBWP.

Please tell me if where i am wrong?

Thanks

Dany
