There's something wrong with the text on my laptop.
Hello pls help 😟 whenever I try to type something on my Calendar, Stickies app, even in facebook chat boxes, there seems to be something wrong with the spaces between the text when I press enter (i think it's what you call the Leading). I don't know what happened but about 2 weeks ago my laptop hung and suddenly the text becomes like these (pls see photos attached) 😟 I've tried restarting my laptop several times but nothing happens. I'm using a MacBook Pro 13" OS X Yosemite Version 10.10.2. Please help! Thank you.
MacBook Pro, OS X Yosemite (10.10.2)
