Anyone know what is causing this problem:

I am using Dreamweaver 8 and when I have finished and close Dreamweaver it takes around 3 minutes for it to shut down.

When it is shutting down it just hangs for the 3 minutes.

I have deleted it and re-installed it but it is still the same.
I am using it with Windows XP.

It happened before a clean Windows re-install and still happens

All help much appreciated
