So, I edited the form created and just changed a field display name, then tried to save the design and again it crashed. perhaps it has siomething to do with access rights. I am running Win & in 64 bit. I will try to run DW as an admin.
Nope, I started DW as an ADMIN and trying to change the form produced the same result. Okay over to you Jason, what's next?

Tried to update using the Preset manager and DW crashed again.
