I think (but it was a long while ago) that the views and hence the view frame property is available through the automation API allowing you to turn them off, but you would have to write a bit of code to do it. I cannot gaurantee this as I don't have access to DMU and it was a long while ago that I had to delve into this area. There also may be an option in the tools options.
Sorry Schamp, I had another license checked with the DM1. Regardless, I get a tree down the side and can shut off the view frame in the property page. I have access to this because I have Catia and Enovia loaded.
Can you right click on the view and access the property page?
