Hello. I've recently started playing Navy Field 2 on Steam and experienced some issues regarding the stability of the game. I've had occasions where when I alt tab, I don't see the Navy Field 2 icon to click back to. Using task manager to switch to the game brings me to the window, and on some occasions the video completely freezes. My input is still accepted since I can hear the clicking sound when I shift between the engine settings, and the sound of battle still plays. However, the image is frozen still and I am unable to play.

Specs:

OS: Windows 8.1 64-bit

CPU: FX-8350

GPU: MSI R9 290

RAM: 8GB (Corsair Vengeance)

I've installed all latest drivers prior to the occurrence of the issue
