How do you append the info to the listbox ?  Do you use WinSendMsg or
WinPostMsg to send the LM_INSERTITEM message to the listbox ? (I assume
you do either that, or you send some WM_USER message to the dialog
box window - the same rule (below) applies in that case).
From a secondary thread without a PM input queue, you must use WinPostMsg.
WinSendMsg cannot be called from such a thread.

Hope this helps,

Peter
