Unfortunetly I can't explain it, because I don't understand it myself. I 
have inserted debug messages on all the places where the listview 
display mode can be changed  and none of them appeared. After going once 
more through the whole code I found this. Obviously it seemed redundant 
and the only reason for doing that was workarounding problems with 
changed WS_VSCROLL and WS_HSCROLL styles (which correctly don't recieve 
WM_STYLECHANGED notifications from the scrolling code). So I tried 
removing it and ... whoa ... to my surprise it started to work.

Yes, I installed it on Windows and even most of done most of the testing 
on Windows with Wine COMCTL32. Before sending the patch to wine-patches 
I checked if it works as desired on Wine...
