Strange change in getch behaviour when mouse click

[Playerdark]

Hi,

I'm not sure if this is a bug or not because I guess it would have 
occurred earlier, but it is a mysterious behaviour for me. I am running 
NCurses 5.9 with Ada on mingw on a Windows Server 2008R2 machine. I have 
a mainloop that reads keyboard inputs. the setup is like so:

      Terminal_Interface.Curses.Set_Echo_Mode( Switchon => False );
      Terminal_Interface.Curses.Set_Keypad_Mode (Win      => 
Input_Line_Window,
                                                 SwitchOn => True );

      Terminal_Interface.Curses.Set_Timeout_Mode (Win    => 
Input_Line_Window,
                                                  Mode   => Delayed,
                                                  Amount => 100 );

I also turn mouse events off in case a mouse is there, but this line 
reports there is no mouse:
      IF Terminal_Interface.Curses.Mouse.Has_Mouse THEN
         Old_Mouse_Mask    := 
Terminal_Interface.Curses.Mouse.Start_Mouse (Mask => 
Terminal_Interface.Curses.Mouse.No_Events);
      END IF;



When I call

Terminal_Interface.Curses.Get_Keystroke ( Input_Line_Window );

this call returns immediately with or without input as it should be. But 
when I click in the command window that runs the application, this line 
blocks from now on until I press a key. I tried to reset the timeout 
mode every time before I read a key but to no avail. Once the console 
was clicked with the mouse, the Get_Keystroke function blocks stubbormly.

I dont think its an expected behaviour but I dont know if this is a bug 
either
