When I after running a capture stop the capture, Wireshark sometimes (pls see
'Note' below) hangs forever and uses a lot of resources. I therefore used the
Sysinternals process monitor and can see that Wireshark keeps trying to read
from the
"C:\Users\<my-usrid>\AppData\Local\Temp\wireshark_2_interfaces_20160119234912_a10072"
and keeps getting "END OF FILE".

When I try the same thing with Wireshark-gtk.exe (Legacy) from the same install
this problem does not happen.

Note: A circumvention for this problem seems to be : Create a new profile
before starting each new capture (and only use the profile once - the same
profile might work several times, but when a profile start failing once it keep
failing).
