Hi J.R Link,
Please go to the Preferences in Lightroom , and then the Interface Tab.
Please change the Font Size, restart Lightroom.
Let me know if it helps.
You should be able to fix it by double-clicking on the title bar (the bar that contains the maximize and minimize icons).
Also please try to press Shift+F key on the Keyboard, 2-3 times, it will show the various full screen mode.
Thank you. That worked. I appreciate your help.
That normally works in Windows, but for some reason, it didn't work here.
Thanks for the reply.
You are Welcome, Glad we could help.
