Sky Bet Championship strugglers Wigan and Huddersfield cancelled each other out in a desperately poor 1-1 draw at the DW Stadium.
The opening half-hour was pretty much devoid of any sort of excitement or entertainment, with neither goalkeeper required to do any sort of work.
Lee Evans was then harshly penalised by the official for winning the ball fairly in the air and teeing up Windass, who fired straight at the goalkeeper as the whistle was being blown.
But as the half looked set to peter out completely, Wigan took the lead with a goal gift-wrapped to them by the home defence.
There was little danger as Grabara tried to play the ball out from the back, only for Windass to step in and intercept.
Windass was then one-on-one with the goalkeeper, and he gave him the eyes to finish easily into the bottom left-hand corner after 43 minutes.
Town almost gifted the Latics a second goal shortly after the restart, and again it would have been totally self-inflicted.
Grabara was left hopelessly short by a poor backpass, with Windass on to it in a flash.
But as the Wigan forward tried to flick the ball beyond the advancing goalkeeper, Grabara got enough on it, and a defender was able to clear.
Fortunately for Wigan, the goalkeeper was able to collect at the second attempt before Grant could pounce.
But the warning wasn't heeded, and the West Yorkshire side did level the scores with 20 minutes remaining.
This time there was nothing Wigan could do, with Grant setting his sights from 15 yards before rifling home a super effort that flew into the top corner like a rocket.
Wigan's attempt at a response saw Windass shoot into the side-netting.
Wigan were hanging on at this point, but they almost pinched all three points right at the death.
However, Town defender Christopher Schindler managed to get a slight touch on the ball to deny the forward a tap-in.
