I suspect you are right about Cocotron being the main problem by not dealing the right way with starting a new copy of Cocotron. We will test this. Meanwhile, I think option 3 is not that unattractive. Our typical CCL app user would not be very likely to use any other CCL based app including Emacs. Also, we could, and probably should, rename "wx86cl.exe" to <ourapp>.exe This would minimize the risk of terminating the wrong process. There may be cases where running multiple copies of ourapp would be useful but this would probably require fixing Cocotron. 

Is there some some simple way to "find all OS processes that have the same name as the current OS process but different process identifiers and kill them" using some already existing set of handy CCL process related functions or will this require the call of straight Win32 functions?
