Whenever I open up another program, Minecraft Windows 10 Edition will continue to work normally, but when I maximize Minecraft from the task bar, it will show a partly loaded Minecraft and the whole computer will freeze up (CTL + ALT + DEL Wont even work, I need to Soft Reset It!)

Drivers: AMD Radeon R7 M260 and Intel Integrated Graphics
Processor: Intel Core i5 - 4210U QuadCore
Model: Toshiba Satellite

(No Error Message could be recovered due to the computer completely freezing)

If it helps, I was also playing on Multiplayer, Hosting the world. Please Fix!
