Hi for PIP02 users PIP02 (latest versions at least) expects a directory C:\STUDIO\CONFIG\ to exist, it is where the config file is created and used. if the directory is not made, ie the original instructions were not followed then the settings are not memorized. it is possible to change the default directory by defining a environment variable STUDIODIR in autoexec.bat : SET STUDIODIR=D:\SOME\ as example, then the config directory will be D:\SOME\CONFIG\ hope this helps at least with some problems. (latest PIP02 uses MPASM supplied INC files to extract fuse information so I hope many fuse problems are solved too.) antti -- Silicon Studio Ltd. -- http://www.sistudio.com
