Typically it uses PostMessage() to execute corresponding IME function on the toolkit thread but if DnD operation takes place SendMessage() is used. The state of m_inputMethodWaitEvent event object remains signalled after SendMessage() execution. That causes failure of subsequent IME functions calls via PostMessage().
