Okay, I'm pretty much new to Mac. I've only had my iMac for about 2 months so there are some things I don't know. I started having this problem recently and don't know where it came from. Sometimes my Trash won't open nor any folder within my Documents Stack folder. I'll click on it and nothing happens. I'll restart my computer and it'll work again but in a few days it starts up again. The last app I installed was MacJanitor, in case that has anything to do with it (I installed MacJanitor because my Mac isn't on all night, I put it in sleep so I run the daily/weekly/monthly scripts through that app). Can anyone help me solve this problem?
