Window bigger than screen resolution

Hi, I have a problem on my MacBook pro with the Sync settings window.
I can not click the “ok” or “cancel” buttons because the window is too big for the screen. Resolution of the monitor is already at maximum.
If anyone could let me know a work around for that issue that would be nice. Thanks
