files lose permissions
Hello!
I'm having a weird issue since installed El Capitan.
It doesn't always happen, but now it seems to be happening more frequently.
My files will, for no reason, suddenly say "you can't open this file because you don't have the proper permissions" (paraphrased).
It happens to jpg, pdf, png, and seemingly every file type. Usually they are on my desktop. One time I was also trying to save a new file to the desktop with Pages, and it said the same thing. Restarting the Pages program didn't help. What I have to do is restart my computer and it seems to solve it, but I don't want to have to keep restarting. I'm not sure why this is happening, and when I look at the permissions, they are always fine. I am authorized even though the message says I'm not and it won't open/save the files.
Any help appreciated.
Thanks!
Kristin
