Problems with the Windows console program "selected Mode"

Recently with Nodejs wrote an agent program, has been using a good, wood has problems, today suddenly found that can not be used, using Telnet to connect the port of the agent can also be connected, but the service is not normal use, prompting the connection timeout. At that time guess is nodejs somewhere blocked, analysis of the code, how can not understand can not be blocked place ah. is a variety of Daoteng, and later found a strange problem, I put the mouse on the Nodejs console, the default into the editing mode, and the entire application of the title into the "Selected XXXX" This form, I want to quit the program, need to press two times CTRL + C, is this the problem? Again to have the test, if it is still the problem, exit the editing mode, the entire application can be used. Hey, tossing a night ah, are some small angry, (Yun-dimensional classmate) Why not do nothing to set the default to enter the editing mode, from the console icon right-click, select Properties, the default into the editing mode of the options are all canceled, Haha, the whole program will not be blocked in the console mouse click. This time the right to accumulate experience, remember not to arbitrarily set "selected" mode Ah, will block the entire application!
