Also, I was using DFLOGM so you were correct on all accounts.

This call is not clearing the box. Should I use something else? I did a test using LB_GETCOUNT and it worked.

My guess is that DFLOGM puts that info back into the listbox soon after you empty it (i.e. LB_RESETCONTENT works but you don't see it). Preferred way is to use DlgSet(Dlg, IDC_LIST1, 0, DLG_NUMITEMS).
