------- Additional Comments From rossi.f@inwind.it 2007-31-03 16:17 ------- So what I can understand from your description is that the wine implementation of the listview header has to be adjusted to reflect the native behaviour.
Is this an easy task or do it need a deep rewrite of the current code? At least you have found the problem :-)
