Right, that's probably the best case for the OP is to detect
if the capslock state is enabled /while/ the person is typing
their password. ie. pseudocode:
case FL_KEYDOWN: {
static int warn = 0;
if ( event_state & capslock )
{ if ( !warn ) { warn = 1;
show_capslock_warning_in_status_bar(); } }
else
{ if ( warn ) { warn = 0; clear_status_bar(); } }
If I understand correctly, the capslock state info is correct during
regular keypresses, just not when the capslock key is hit.
