I think I already found the (apparent) difference in the events, the (not) hanging in the OnLButtonDown. I need to find out why it doesn't stay in there and if it's in listview, message, events...
The mouse tracking in listview happens in the LISTVIEW_TrackMouse() function, which seems correct. It is getting called from only one place (in LISTVIEW_LButtonDown()) so a few print statements there would be nice to see that (1) it is being called, and (2) that it doesn't exit prematurely.
I made a test and added a printf message in the loop of TrackMouse. When I hold the mouse button in the first column I see hundreds of these message pass by. But when I press on another column I don't even see it enter the whole function TrackMouse, not to mention the message from the loop. In LISTVIEW_LButtonDown the nItem is -1, so it thinks that no item is selected and skips most of the code.
I'm still looking at logs. But I also thought that LISTVIEW_HitTest gave wrong results for other columns (LVHT_NOWHERE) but I still need to look further. But that might go along with the listview thinking that no item is selected.
Thanks for your hints, give me new ideas.
