Changes? Absolutely NO changes. Only, a bug in the ARP docs caused and incredibly wide range of problems, from memory completely wiped (including the backed-up battery clock) to a simple crash-on-exit. Now, thanks to Christopher A. Wichura, the 1.01 code is ok. So, even you, if you're using ARP, beware: ARPALLOC() DOES NOT PASS ANY TRACKER BACK THROUGH LASTTRACKER!!!! You must use the memory pointer you get as a DefaultTracker *, too. Or you'll get a NULL tracker pointer... The same holds for ArpAllocFReq(). Seba P.S.: V1.02 was shipped because of a bug in my ARP bindings. Sorry. Under certain conditions a few bytes were not freed.
