Phil,

I've been running my program using safe mode memory handling and one 
thing that came up is in the EGW_OnParentEvent routine around line 3350 
there's a call to the fetch() routine in tk_mem.e that passes the lParam 
parm and the diHwndItem.  I was under the impression that the lParam was 
not a pointer but a value.  In the fetch() routine a peek4s() is being 
done at s[1] + struct + s[5].  If the lParam is a value then wouldn't 
this be a problem?  If it's a pointer then I need to go back to the 
win32lib docs!  

I didn't get any further than that.  What I did was I created a version 
of tk_mem.e that uses the Eu allocate() and free() instead of the 
windows memory routines.  I then used safe.e in place of machine.e.

I'll keep looking but I thought you might like to know...
