I am working with a clean install of OS X 10.7.5 (Lion) and Scribus 1.4.3.
For a couple of days, everything was fine. But I now find that the active document window does not render at all. Splash screen and dialog boxes are unaffected. I can only see the Scribus window with an open file in it when using Mission Control (or F3) and looking at the multiple desktops. As soon as I try to make it active it disappears. I have tried reinstalling Scribus, opening new and existing files, but nothing changes. (Quietly frantic as I work on a deadline)
Most grateful for any help.
