Now that I know that the problem appears only when the McAfee antivirus is there, I could fix it.
I am sending a corrected version of the OBJ files directly to Rod, a "DIFF" of the sources directly to John, and I'll include the fix in the next release. If some of you need to have the fix sooner, please ask me directly. JY PLEASE READ THIS IMPORTANT ETIQUETTE MESSAGE BEFORE POSTING: http://www.catb.org/~esr/faqs/smart-questions.html
