Is there a way to stop this ability, but still be able to minimise if necessary?

Did you try Google? A quick search gave several hits stating that the only way is to suppress the WM_NCLBUTTONDBLCLK message:

Code:

      INSTALL @lib$+"SUBCLASS"
      PROC_subclass(WM_NCLBUTTONDBLCLK, FNdummy())
      DEF FNdummy(M%,W%,L%) = FALSE

      SYS "ShowWindow", @hwnd%, SW_MAXIMIZE
      SYS "GetWindowLong", @hwnd%, GWL_STYLE TO ws%
      SYS "SetWindowLong", @hwnd%, GWL_STYLE, ws% AND NOT WS_MAXIMIZEBOX

      REPEAT
        WAIT 1
      UNTIL FALSE

You could probably argue that being able to double-click on the title bar even when the maximize box is disabled is a bug in Windows, but of course they can't change the behaviour now.

I didn't. However, even now looking it up specifically, I'm afraid the understanding is a little beyond me at the moment. Hopefully, the more I learn...

The code you supplied works fine in my program, thank you. Until I get time to examine the principals within it more closely, I will use the appropriate lines 'as is'.

Thanks again.
