Symptoms

When working on a workflow process there is an issue with Silverlight. What is occurring is that when renaming a workflow step from the design screen there is a Silverlight pop-up that asks for permission to access the clipboard, this occurs after using the letter 'v' in the steps name. This can be worked around by accessing the workflow step and renaming it from the wizard.
 

Diagnoses

What appears to be happening is when using this particular letter, Silverlight is assuming that the CTRL - V command is being utilized and asks for access to clipboard.
 

Resolution

The workaround for the time is to rename the workflow step from the event wizard. Another option to fix this issue is to accept clipboard access, this will fix the pop-up prompt for the current design session.
