★★Why is the object automatically unselected after the command is executed in ZWCAD

Issue:

After select the object and execute the command, the originally selected object is unselected, and need to select it again.

• Solution 2: 
  Input the command OPTIONS and press Enter to open the Options dialog box, then check the option Noun/verb selection in Selection → Select Modes.
