Why does screen sometimes moves over to another screen & other things?
I work from home laying in bed with my knee crossed over to prop up my MacBook Air 2017. Sometimes I'll be typing away & it will move over (literally - it slides over) to a new blank screen (will it shows things I have on my desktop but nothing I have open). After years of loosing documents that were open & I was working on I finally realized I could click onto one of the apps & go back to the original screen.
WHY is this happening??????
