Cygwin 64 in windows 10 always stopped with Ctrl-C when select text with mouse

Recently upgrade to windows 10 (64bit), and notice Cygwin 64 terminal mintty always stopped with Ctrl-C when select text with mouse, be it in shell command line, or sqlplus/rman comand line, cause troublesome of copy/paste function.

Initially I thought it is problem with mintty, until one day I can't bear it and google it. The article 

Cygwin alway's interpreted with Ctrl-C saved my cygwin. 

Finally I found I have a startup dictionary called YouDao. No more Ctrl-C for mouse selection, after I disable all functions of the dictionary's mouse selection functions.
