Has anyone noticed that multiple select tree controls don't work correctly under Vista? You can see the behaviour by following these steps:

1) Open the tree control sample under vista
2) On the left side tree control select the first item then press the shift key and select the last
3) Problem 1: the first item is deselected and the rest are selected
4) Now deselect everything
5) Select the first item.
6) Press the control button and click on the third item.
7) Problem 2: The control button is ignored - the first item is deselected and the third item is selected.

Pretty serious problems for those of us depending on the multiselect features of the tree control to get the job done in our application.

Thanks!
Karim

We have seen the same problem with the multi-selection feature of the treeview control on Windows Vista. Can someone at Codejock please let us know the status of a possible "hot fix" for this problem?

This is a critical issue for us to get resolved ASAP.

Hello,

Yes, thanks for this notes, indeed in Vista standard tree control have another behaviour when SetitemState called, than all previous OS.

We modified our sources to make it work, please wait next release or open issue I will attach changed file.
