Hi,
Are you selecting the file from main grid or preview pane when running the command "View in Window"? If file is select from main grid, then the latest version will be opened. Otherwise, the particular version selected in preview pane will be opened. For instance, when version "2" is selected in the slide of View tab, click Open button, then version 2 of the file will be opened with TrueView. Attached is the picture for illustration.
Thanks,
Carol
