[ solved ] Can RichEdit control create a right-click menu?

[wyf]

Hello everyone! I am asking for help. Can RichEdit control create a right-click menu?
Try to use GUICtrlCreateDummy() to create a dummy control,
Trying to use GUICtrlCreateContextMenu again has no effect. Can anyone help me? Thanks!

works for me only in x86 mode (even 1 have a x64 win10 version).
