@DNA Thumbs drive,
From a dog breed website....."Exercise is of paramount importance for these tireless, energetic animals. They are more than a match for even the most active family and they should not be taken on as family pets unless they can be guaranteed plenty of vigorous exercise. They need to be taken on a daily, brisk, long walk, jog or run alongside you when you bicycle. If under-exercised, this breed can become restless and destructive...."

My suggestion would be to find some quick and effective way to get her running. You're right in that Pointers need to be worn out at least twice a week, with long walks on days in between.
OK.....
Does she go for a tennis ball?
Do you have a reasonable size back garden?
Is it escape proof?
Is anyone available during the day to chuck a ball for her? Take her for a good, long walk?
There must be a way somehow to get her up and around each day.
My original boredom thought is what is probably making her whine.
