Argh! I cheated. I used a slightly older Wine and copied the comctl32
dll there. Today I retested with CVS Wine plus the latest X11 patch and
got it to work by just replacing the shell32 library with an older one.

That one is fixed by X7 and it still works with X11. The columns are
left aligned :-)

I generated a log of the Winzip 'crash on exit'. You can find it there:
http://fgouget.free.fr/tmp/listview2.log.bz2 (2.7MB)


Also I am getting a crash when I resize the WinZip window:
fixme:listview:LISTVIEW_SetColumnOrderArray iCount 9 lpiArray 0x406828a8
wine: listview.c:1639: LISTVIEW_GetItemOrigin: Assertion `nItem >= 0 && nItem < infoPtr->nItemCount' failed.

Now looking for alternatives to WinZip since it may not be so good for
testing.

The above three can be reproduced in notepad's open dialog by putting it
in 'Details' mode.

That one can be reproduced in Notepad's open dialog too.

These two can be reproduced by putting the Control Spy listview in
report mode (notepad's open dialog is not suitable because it does not
allow multi-select).
