I haven't been following the recent MPLAB thread, but I've just downloaded 6.0.20.0 version and installed. It refuses to open ASM files with content - in fact it crashes= with a fault in srcvw3.dll according to XP. If I change the file type= ending to anything other than dot asm it will load. It will also load if= the dot asm file is empty, but not with code. I have re-installed and wiped registry between times even= disabled ZoneAlarm and AGV anti virus s/w Weird!
