我用mfc寫了一個richedit類，是從CRichEditCtrl繼承來的，代碼很簡單，生成dll給exe呼叫。
測驗發現：
1.在win8,win10,windows2012,windows2016上，只要第一次在richedit的框里點一下滑鼠，整個視窗就會假死10多秒，沒有回應,然后就正常了。
2.winxp win7 win2003 win2008下怎么點擊都正常。
3.把CTraceServiceControl類直接寫到exe里面呼叫，一切正常。
監視richedit的訊息，點擊后，會收到MSIMEQueryPosition（行號000236），這里要卡很久，然后才是000237，應該是和輸入法有關，請問誰有辦法解決嗎？感謝大家

卡住的時候點"暫停", 然后看callstack, 看卡在哪uj5u.com熱心網友回復：
沒準只是因為少某個字體。我猜。或者控制元件注冊不對。
uj5u.com熱心網友回復：
在64位Windows下：64位exe和dll在目錄c:\windows\system32目錄下；
32位exe和dll在目錄c:\windows\syswow64目錄下；
所以要注意：
在win64位系統下注冊32位ocx或dll需要將32位ocx或dll拷貝到c:\windows\syswow64\目錄下。
且注冊要用c:\windows\syswow64\regsvr32 xxxxxxx.ocx或dll

直接在exe創建一個繼承類，是沒問題的，所以字體，控制元件原因可以排除uj5u.com熱心網友回復：
