[Qt-interest] Problem with selection in QTreeView

[Ιντζόγλου Θεόφιλος]

I have a problem with selection in QTreeView. I am using the ExtendedSelection 
mode so I can use ctrl and shift while selecting item, however if I try to 
make a selection dragging the mouse from any item to any other item, the 
treeView seems to get stuck at selecting the first item. I can't change the 
selection to another item whatever I do. I can just create new selection that 
all have to start from the selected item. :-( Any ideas about it? The code can 
be found at my project page in svn 
http://developer.berlios.de/projects/mediatagtools/.
Feel free to ask for any other info you may want. Thanks in advance!
