    NH> Hello, MBSE Developer Team,   
      
    NH> I have found and fixed an error with the 'HelP' window shown in the   
    NH> internal editor, which causes the editor to crash:   
      
    NH> 1.) Steps to reproduce:   
    NH>     - Enter a message in the internal editor   
    NH> - In the editor, press  and then  to display the help text   
    NH> window - Press a key to close the help text window - Try to continue   
    NH> to edit the message text -> an error message appears, then the BBS   
    NH> disconnects   
      
    NH> 2.) Root cause analysis:   
    NH>     - The function "void Full_Help(void)" in fsedit.c utilizes several   
    NH> helper functions to draw the help-text window. These helper functions   
    NH> access and manipulate the gobal variables "int Col" and "int Row"   
    NH> causing an overflow of the "Row" variable. This overflow will lead to   
    NH> a Segfault when "Refresh()" function is called before resuming editing   
    NH> of the text.   
      
    NH> 3.) Solution:   
    NH>     - i've added tow local variables "int hc" and "int hr" to the   
    NH> function "void Full_Help(void)" which are being used to temporary   
    NH> store the original values if "int Col" and "int Row" at the beginning   
    NH> of the function before drawing the help-text window. Once this is   
    NH> drawn, "int Col" and "int Row" are being assigned the original values   
    NH> temporarily stored in "int hc" and "int hr". That way, the call to   
    NH> "Refresh()" after drawing the help-text window will no longer crash   
    NH> and operate as intended.   
      
    NH> Do you want me to create a MR for this fix?
