I wanted to transfer files from USB flash drive to Halo internal storage. But after clicking on "copy file" in default file manager, the app either crashes or restarts itself. Anybody experience the same?

I'm using Halo on latest firmware. All my applications are updated. Was using a 64gb SanDisk flash drive.

Is it normal to have a black light where the projection would have been after keystone correction? For example, I set my halo about 20 degrees off from center, resulting in a projection that is trapezoidal. After manual keystone correction, image is fine, but black light still fills the area where the trapezoid was.
