I may know a trigger condition for the freeze: door closing.

Freeze minute ago happened when door closed in front of my face
(it got half closed before freeze).  I think on previous freeze it
happened when (another) door started to close when I went under it,
and on first freeze door may have started to close behind me after
I had gone through it (and were further away).

I see also wrong keys being triggered, e.g. ESC when mouse is moved
(as I get to menu).

As BM doesn't anymore work with latest Hatari WinUAE CPU core when
cycle accurate mode is enabled, maybe there's some timing issue.
I.e. this could be Hatari issue.

If it doesn't happen on real device, I wouldn't pay too much attention
on this until it can be reproduced with cycle-accurate Hatari WinUAE
CPU core.

PS. Except for the HW MIDI replay modet, I think BM config should
be default one.
