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... Jonas Phil Russell wrote: > Jonas, > > Yep - very weird.
