When opening the Vault and browsing through pdf's, the preview window is not always the same.

(dont mind the white blocks, I created them)

preview 1:

PDF-producer: Adobe PDF Library 10.0

PDF-version : 1.5 (Acrobat 6.x)

Preview 2:

PDF-producer: SolidWorks PDF Publisher

PDF-version : 1.4 (Acrobat 5.x)

in preview 2 the preview is useless. How can we use preview 1 everywhere?
