Tried to open a quark file on disc and Quark crashed. Now if I create a new document it will not save (unknown error - 30871) - if I try to open any existing document it crashes on opening. Quark seem baffled. Had me throwing away extensions, Jaws folder, etc and re-installing but all to no avail. Quark managed to make it work in Safe Boot but not in normal mode. They've gone away to think about it. Anybody else any ideas please.
