I've just opened T2 to find a total blank where my list of current and library projects and edits ought to be. There are just the headings "Current" (or whatever - I'm on another computer)and "Library" but nothing underneath at all, and a minus sign next to each heading. Clicking the minus sign simply turns it to a plus sign, but still no projects appear.
Fortunately I know where they all are and can restore them one by one, but what the hell's happened? And BTW I haven't done anything unusual, defragged, installed or uninstalled anything in the last few days.
