it\"s not a big problem but it\'s quite strange: the cal3d models must be about 2kb big and, in fact, the updater require a lot of time (like if it was 2mb (if you understand wat i mean))
NB : if there is already a post about that bug (and it could be possible) I would be sorry but wont feel responsible of the double post (i searched and fund no useful post with cal3d in its title).
