I wrote a richedit with MFC class, from CRichEditCtrl inheritance, the code is very simple, to generate DLL to exe calls,
Tests show:
1. In doing, win10 windows2012, windows2016, as long as the first time in the frame of richedit click the mouse, the whole window will feign death more than 10 seconds, no response, and then the normal,
2. Winxp Windows 7 win2003 win2008 under how to click on normal,
3. Write CTraceServiceControl class directly exe calls inside, all is well,
After monitoring richedit message, click, will receive MSIMEQueryPosition (line number 000236), to card here for a long time, then 000237, should be related to input method, could you tell me who can work it out? Thank you
