--- Comment #16 from Chituc Georgian dianaxxyyzz@gmail.com --- Hello , I've created a lot of cases ,like photoshop , that reproduce the tool tips stealing focus and not dissapearing and for me this paches fixed it .
The code is simple , and extreme wine developers can inspire and rewrite the patches how they think it is the best . The idea for tool tips ,to do not stealing focus, is that every window created that has the class TOOLTIPS_CLASS , has to have a WS_POPUP style , or it will steal focus . And also the tool tips that are created via CreateWindow ,and are managed by the window manager, and refuse to dissapear , must be hidden using the ShowWindow( hwnd, 0 ) , or they will refuse to dissapear.
