--- Comment #2 from Zhiyi Zhang zzhang@codeweavers.com --- The Task Dialog implementation was written before Command Link implementation. https://source.winehq.org/patches/data/169017 should make it better. And also the first command link is changed to a push button at start because of WM_NEXTDLGCTL and DM_SETDEFID implementation doesn't have Command Link in mind either. v5 and v6 common control have different behavior. See https://source.winehq.org/patches/data/169019 for details. I will write a patch once I figure out a proper way to implement it.
