Hmm, you see I have no issues on Windows 7 on my laptop. I've also just loaded up a virtual machine via BrowserStack and no issues there. I'm inclined to believe this is specific to your setup, particularly as there have no been updates for a long time. I just don't have any idea why.
Do you know your desktop resolution? And a screenshot would be great.
PS. I know you've probably only recently moved to Windows 7 but have you considered upgrading to Windows 10 considering it's free for you and done online? It's pretty great for laptops as it's very lightweight.
I've had Windows 7 for at least five years now, and I do know about 10, so might still consider it. I've had my laptop for four years though. I'll give resolution a try, but if that doesn't work then I'll just accept the problem.
