Tree

I'm using Wine 1.1.17 (compiled from source using gcc version 4.3.2 20081105
(Red Hat 4.3.2-7) ) on Fedora 10 i386.

The problem is in CATIAV5R19 with tree (attached image) in main window and this
is very annoying:

1) LMB in drawing area to lose focus on tree
2) LMB on "plus sign" in tree
behaviour:
nothing does happen
expected behaviour:
tree should unfold
3) move mouse pointer and tree unfolds as it should earlier

1) LMB in drawing area to lose focus on tree
2) LMB on "plus sign" in tree
behaviour:
nothing does happen
expected behaviour:
tree should unfold
3) LMB on "plus sign" again and tree unfolds but if i move mouse pointer the
tree folds again which is unwelcome

LMB-left mouse button
