E-mail Options button falls outside of screen

Hi,

Please look at screenshot. I had been troubleshooting this for 2 hours because i thought the Options button (for using an e-mail template etc) didn’t work but after all that time i discovered it falls outside my screen and i just have to use the horizontal scroll bar to make it visible. My screen is super wide, i see no reason why this panel would be placed outside my screen. How can i fix this? Is this a resolution issue?
