1. When clicking on Grid option "Shown", a JavaScript error message appears: "Map image update failed". Map grid doesn't get hidden.

2. Sometimes after changing icon label and pressing the "Apply" button in map properties dialogue host icon label doesn't actually change.
For example, icon label was "

{HOST.NAME}

\n

{HOST.CONN}", changed to "sdfsdfdsf\n{HOST.CONN}

".
