(From the most recent DELPHI digest) : From: MACWEEKBOS : Subject: Re: Vaccine and Font/DA Mover (Re: Msg 26280) : Date: 14-APR 13:44 Network Digests : : I just tried to cause a problem running Font/DA Mover 3.6 with Vaccine : installed. I tried it with both System 4.2/Finder 5.1 and the current : System and Finder and could not get Vaccine to trigger, although it : could be triggered by other programs. : : Ric Ford I have MacNosy'd Vaccine a little, and it looks as if Font/DA Mover may well not trigger it. Vaccine doesn't seem to look at whether the System file is being modified; rather it looks at the resource types instead. The traps AddResource and ChangedResource are patched, and Vaccine is triggered if the resource type argument is one of the following list: INIT, DSAT, PTCH, CODE, MDEF, WDEF, CDEF, nVIR, PACK If you are not modifying a DA with one of these resources then you should not trigger Vaccine. Disclaimer: I don't remember whether there were some other traps patched which I didn't examine; so maybe there is another check for whether certain files are being written. /JBL UUCP: {backbone}!bbn!levin USPS: BBN Communications Corporation ARPA: levin@bbn.com 50 Moulton Street POTS: (617) 873-3463 Cambridge, MA 02238
