          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

Hello,

I've developed dll for Windows that uses tree view control. This is working
fine under Windows but under Wine the control auto-collapses.

For example you have expanded branch with several sub-branches. When you click
with the mouse on one of the sub-branches you are navigated to another window.
Then you click again on another sub-branch in the tree view window and the main
branch collapses (as if the branch [-] control is clicked).
The tree view style is TVS_HASLINES, TVS_LINESATROOT, TVS_HASBUTTONS,
TVS_DISABLEDRAGDROP, TVS_NOTOOLTIPS, TVS_SHOWSELALWAYS, TVS_SINGLEEXPAND

With the original Windows XP comctl32.dll this is not observed.

Thanks,
Pavel
