c - Why do my owner data list view state images come up as blank on Windows XP? -

simple problem time, 1 i'm not seeing on searches: have list view control state images should show in 1 column. in wine, windows vista, windows 7, , windows 8.1, things correct. in windows xp, state images don't show up, showing white space image should be. common controls version 6 required. doing wrong?

here sample program demonstrates this.

the listview control uses lvm_setcallbackmask make request item state data via lvn_getdispinfo.

i can guess on windows 7 , upwards requirement removed owner data controls - docs don't - in xp/vista need send message have request item state.
