I am not able to reproduce the problem that you are reporting.
Do you have other WebAssist Extensions Installed? if so what version numbers?
Have you tried Deleting the Dreamweaver Cache file from the users configuration folder:

If you continue having a problem, provide a skype user name or US phone number in a private message, and I can look into it with you.
