this is the first time it has happened to me, but the button in the following dialog has no text on it 

, sorry i cant post a screenshot 

dialog msnlogin {
  title "Login"
  size -1 -1 120 48
  option dbu
  text "Email:", 1, 3 11 17 8
  box "Login", 2, 0 -1 120 49
  edit "", 3, 21 10 96 10, autohs
  text "Password:", 4, 2 25 26 8
  edit "", 5, 30 24 87 10, pass autohs
  button "Login", 6, 41 36 30 9, flat
}
all my other dialog buttons have text, that is the only one that doesn't.
the only /did -r's and d's are here:
    did -d msnmsgs 2 $didwm(msnmsgs,2,$+(*,$replace($4,$(%20,0),$chr(32)),*))
    did -ra msnmsgs 19 $iif($2,$ifmatch,None)
which obviously dont remove that text.
