--- Comment #19 from Hin-Tak Leung htl10@users.sourceforge.net --- The functionality of the linux version is quite limited - for example, text extraction does not work; nor printing to more than one pages.
Anyway, as I wrote, the crash is not caused by or specific to file opening, but by how you open it (via menu->open, or via the button icon).
Besides, I am sure specific aspect of poorly engineered windows software is not limited to just CAJViewer. The menu->open issue looks a lot like another crash from another unrelated software, which can be work-around by using genuine Microsoft gdiplus.dll (not in this case) - that certainly suggested that it was screen-drawing / tooltips-overlay related.
