    The what I can find on SysWindow handling (SysWindow)
    The SysWindow component provides access to the window handling of the graphical environment. The target visualization typically runs in a window.

    There is more info here on page 450.

    It reads like it handles the target visualization window by using the window manager in the OS.

    Maybe either something is not functioning correctly in the linux environment or there is something different in your linux distro so that Codesys is no longer able to work with the window manager.

      Hi,thanks for your reply.I just have no method to solve this problem.
      Those codesys errors do not appear everytime,means that the errors occured randomly .And when i changed the codesys's code and download to the board,this also may make the sceen black.When the screen is black,the same appearance of codesys is "ExceptionSysWindowSingleTask".Here i post the CODESYSControl.CFG file.
