these 2 controls.

case wm_create:              hwnd chatbox_cntrl;             hwnd message_text;              chatbox_cntrl = createwindowex(ws_ex_clientedge,"edit","",                 ws_child | ws_visible | ws_vscroll | ws_hscroll | es_multiline | es_autovscroll | es_autohscroll,                 0,0,240,260,hwnd,(hmenu)chatbox,getmodulehandle(null),null);              message_text = createwindowex(ws_ex_clientedge,"edit","",                 ws_child,0,270,240,10,hwnd,(hmenu)messagetext,getmodulehandle(null),null);          break; 

the message text window doesn't have same style flags first. specifically, missing ws_visible. problem.
