Hello, a couple of weeks ago I made a posting about my problems programming FB with MacsBug coming up every time I reached a certain condition in dealing with scrolling lists. MacsBug reported problems with a 'Scroll CDEF'. In a pascal-group I read that there are more people experiencing similar problems with lists/scrollbars when using their programming evironment/compiled apps on a 68040 Mac with MacOS 8.1. Anyone on the list also had such problems lately, has deeper insight (and is willing to share ;o) or knows about a workaround? On my Q650 I went back to MacOS 8.0 and had no problems since then. Thank you, chris +------------------------------------------------------+ | ChatWorks Chris Henkel mailto:chatworks@... | | http://ourworld.compuserve.com/homepages/chatworks | +------------------------------------------------------+
