Workflow Window should close automatically

I have three different workflow for document info records for different purposes.I always start my workflow

from object service icons->Workflow->Start workflow.

From the list of list of three worklfows select the workflow and click on start of start with detail.SAP display messages in the status bar "Workflow Started" and Then close the Window.

My Requirement is to close the window automatically once I start the workflow.

Becasue sometime our business user does't pay attention to the message in status bar and they again click on the workflow. Means they are firing hte workflow more than once.

How Can I close the window automatically once I start the workflow.
