Ok, tried again and all this stuff is present. Icons are displayed so II'm sorry, no clue then. You can try to open a PDF file, the renderer is completely statically linked to the application. If this fails, the problem is probably the mem.ldg but not because of its design but because of the "interprocess" communication, IIRC, it has some stack constraints.
guess it finds and loads the codecs. But the problems are exactly the
same. A couple of "unknown error" at startup, and nothing happens when I
try to open a jpg.
