i only use Quark in classic mode, everything else i need is in OS X. but every 2 hours or so, Quark just jams or something. i get a message saying that there was some 115 error and it couldn't access the network. i seem to get this consistenly, about every 2 hours. once it does this i can't work. it won't let you do anything except save, and then you have to quit and open it again. anyone know how to fix this, or what the problem might be?
