Extended keyboard: Numeric keys not responding
Numeric keys do not function - i.e. "0" thru "9" do nothing when trying to use on Calculator app. Was working fine until I tried to use the keypad a few days ago. I checked USB connection from iMac to KB and transferred the USB port on the rear of the iMac. Re-started Mr. Mac. No change. BTW Sys S/W is Maverick OSX 10.9.5.
iMac, OS X Mavericks (10.9.1), 21.5", 3.1 GHz i7
