I have recently upgraded from Draftsight 2015 to Draftsight 2017 SP1, and now when I type a command shortcut in the keyboard there is a noticeable delay in the command being acknowledged. If  I enter a keyboard command and quickly use my mouse to enter something I find that the keyboard entry is popping up as an entry in the command line. I did not have this keyboard delay with DS 2015, and it now means I have to wait after every keyboard entry to be sure the software has acknowledged the command before I can use the mouse to select an object, etc.  Is there anything I can do to adjust the response time from the keyboard, or any ideas where the time lag comes from?
