--- Comment #17 from Hin-Tak Leung htl10@users.sourceforge.net --- It can crash without even trying to open a file - e.g. you can select one of the menu->help->version(?), for example, just hoping to get version information about the viewer.
There are two ways of opening files, from the menu->open, or using one of the button icons a little below the top right. Using the button icon to open files does not crash; hence my point.
