It only works when that dialog is in the foreground (techinically, when
it's
the active window) because an inactive window cannot receive a BM_CLICK
message. (It thinks it came from the keyboard, but the focused window is
the
active window, and only the focused window can recieve keyboard input).
Change to using BM_SETCHECK message. (Didn't I say that before? It's deja
vu
all over again.)
Also as a matter of style, don't use "0" and "1". Use %BST_CHECKED /
%BST_UNCHECKED. It will be a lot easier to maintain the program that way.
(FWIW, the hWndParent code in there does nothing).
