Small optional suggestion for this section: making ""dummy"" window visible and not overlapped with main window is more illustrative and gives chance to experiment with closing both windows. So I would add additional call to GUISetState(@SW_SHOW) before switching to main window and correct initial coordinates of dummy window. This part is IMHO, so feel free to ignore, while code snippet must work properly to not frighten newcomers such as me." Bug closed Documentation 3.3.14.2 None Rejected
