yesterday at the morning restart of the pc I launched inventor and I tovato the menus in this state (see jpg attached)
should be a corrupt font but what idem for autocad.
advice?
to me it happened, on a pc that had already problems of his, to find me the characters of unreadable uinzozz after launching ccleaner for cleaning the register.. .
from what you tell me, likely you have the same problem
try to launch the font map and see if some fonts are "errated"
