UE4 Freezing

Couldn’t Figure out where to put this. I just downloaded UE4 today, and was messing around with some stuff. If I do anything that initiates a pop-up message such as enabling tile editing on world info or deleting objects from the basic blueprint creator, the whole client will lock up and freeze resulting in me having to force close. Any ideas?

Setup:
UHD 4k
Nvidea GTX 970M
16GB RAM
265GB SSD + 1TB SATA
5th Gen I7 5700 HQ 2.7GHZ
