--- Comment #18 from Nikolay Sivov bunglehead@gmail.com --- (In reply to Wagner.a18 from comment #17)
Hmm but if I use the native version of comctl32 there are many other things which are not working correctly... Are there any plans to improve the builtin wine version of comctl132 to be able to handle treeview correctly?
Sure, somebody has to look into it. And without any way to test it's difficult to do.
