Preview sticky notes
Hi, my sticky notes on Preview are being obstinate. For the ones that I have created and saved on the PDF already, when I click on them to open them, they open and they stay open on my screen no matter what page I scroll to. This glitch started happening 6-8 months ago, no matter the PDF I open. If I exit the PDF and come back, the stickies are closed again. I am not able to add new stickies--it just jumps to another page. Is there any fix for this? I am updated to the most recent OS (if I remember correctly it began happening after an update 6-8 months ago).
