FSX...Windows 10...Screenshots

Good morning all...
I can not take a screenshot by pushing the "V" Key in Windows 10>FSX>Full Screen...
When I uncheck the Full Screen View I get the smaller screen and then can take a screenshot...In Windows 7 I could take a screenshot in the Full View Screen...
Not sure what the problem is...I have the newest NVIDIA Driver downloaded...
FSX Resolution set at: 1024 X 768 X 32...gives Full Screen View...
