XnView Software

hi people,

i've used XnView for many many years on both mac and pc.
i'm totally "mac" now, and I've noticed one bug in particular that
has been here thru 3 OSX changes and many XnView upgrades.

When I'm in thumbnail view mode and I double-click a thumb-nail,
the larger, individual image opens in its own "tabbed" window, which
is highlighted as "active" at the top of the screen.

If I go back to the thumbnail screen (as "active" now), I can safely
close the individual image screen.

However, if I try to close the individual image screen, while still
"in" that screen (tab is active at top), the program crashes.
This has happened in XnView / Mac for several years now.
I've learned not to do it, so there is a work-around for me, but
it would still be nice if it didn't happen.

(here's another small request: it would also be handy to know
which THEME was active with a little check-mark beside it, as
you can see by the check-mark indicating which LAYOUT is active.)

Thanks for an excellent and very helpful app!

OS: mac 10.11.6 / el capitan
XnViewMP Version 0.84 x64 (Jan 13 2017)

I can't reproduce the crash, i open an image in view mode, and close it.

How do you close it?
