After upgrade to desktop 15 windows is letterbox?

Upgraded to version 15, and now my Windows 7 image is letterbox. How do I restore it to full screen?

 

Dragging the corner of your VM dosen't make it larger? Have you tried checking the settings under Actions> configure> Options> Full Screen >Advanced settings>Scale to fit scree: AUTO? Or you can try upper left hand corer inside your VM:

 

Well, am in full screen mode, so no corner to grab. The green button gives me letterbox, black band at the top and bottom, will try the advanced setting when I have a chance later today. Will also see what the Windows system thinks the resolution is.... Before the update to 15, the VM was fullscreen, so was 'assuming' some default in 15 changed and I am just not seeing it....

 

Thanks, the Advanced Settings>Scale was no longer set to Auto. That fixed it.... Appreciate your help.

 

Your welcome, I am glad that the information was helpful.
