Rene, I built the root libraries using ftp://root.cern.ch/root/root_v3.05.05a.source.tar.gz and my problems have become worse. I now getting "user breakpoint called from code at ..." messages - disassembly window shows "int 3" instruction. Problem occurs when I attempt: gSystem->AccessPathName() Note: I have not put in any breakpoints..
