I have a strange problem with the FMC on the 737NG 600-900. I am un a ble to use the . 0 +/- keys along the bottom of the number pad on the FMC. No matter how far below those keys I go it still has 7,8, or 9. Now in all fairness I dont fly the 737ng as much as I used to but I cant recall having this problem before. If anyone has a suggestion I would love to hear them.ThanksAndrew

Usual problem with incorrect FMC keyboard operation is due to display resolution that is not 4:3 (ie 1024:768, 1600:1200 etc). Hope this helps.

Well that fixed it. Thanks Dan. Also thanks for all your procedures you do for the PMDG aircraft.
