The callbackMask is used to determine if a style that a program want to modify is handled by a callback. In this case there is no reason to do something.
NMTVDISPINFOA callback; HWND hwnd = infoPtr->hwnd; - mask &= wineItem->callbackMask; + mask &= ~wineItem->callbackMask; if (mask == 0) return; My 1 line patch changes the test in TREEVIEW_UpdateDispInfo. mask is a flag with the properties you want to change, callbackMask is a flag with the properties handled with a callback. So in my opinion this test was wrong. The change I made fixes eMule, now the statistical treeview displays correctly. So I think my fix triggered another bug now rather than it being wrong.
