ENM_CHANGE is 1 (Google is your friend). I think the ENM constants are the
same as the corresponding EN_ ones, but I didn't check.
You'll have to define constants:
EM_GETEVENTMASK = #0459
EM_SETEVENTMASK = #0469

v0.60.6 is the latest version, and Judith's is an adaptation to IDE, 
specially for Win98 users. There may be a newer release some weeks ahead.
