Copy and Paste not working with Omnissa Horizon client. Darn it Nearby Share!

I work pretty heavily in a virtual machine that I connect to through Omnissa's Horizon client. I very often need to copy and paste from my host machine into the virtual machine. Today, I turn on my laptop and notice that copy and paste no longer works this way. Also, I've got this annoying tile that comes up at the top of my monitor that says "Drag and drop to share..." blah blah blah. A little bit of searching and I find several posts from other people like me, who have had this Nearby Share garbage randomly enabled on their system. So I figure out how to turn it off... System > Nearby Share > toggle Drag Tray off. Great, except I still can't copy and paste into Horizon client anymore. Copy/Paste works well every other way except, even through RDP, but NOT in Horizon client now. Only change on my system has been this random feature turning itself on. How does one go about fixing this? Anyone else out there experiencing a similar problem?
