Hey, I've got a strange problem and it only happens when the computer enters sleep mode, the things that are happening are: chrome opening but being just a grey box, youtube or any other video player on an already open tab not working, messages/facetime not opening and apps failing to respond when opened, all of these things are fixed after a restart but it is just getting annoying having to restart the computer every time I want to watch a video, this is a strange problem and I'm wondering if anyone is having similar problems, or it is a result of something that I haven't installed properly, any feedback would be greatly appreciated, thanks.
