Hmmm, I don't know why I assumed the correct way was to use ++ and -- ....
Maybe so the calls can be interleaved ? If the user issues the code:

freeze_mouse_flag=TRUE;
update_dialog(foo);
// draw some stuff
freeze_mouse_flag=FALSE;

and the dialog contains a widget that does:

freeze_mouse_flag=TRUE;
// draw some more stuff
freeze_mouse_flag=FALSE;

then this will lead to the second drawing be unprotected!
The Right Way(tm) to do things whould really be ++ and --, no ?
BTW, that's why I ever disliked the cld and std opcodes, since they don't
do ++ and -- even :(
