It should reset the OS, just like on real Amiga hardware. Not a complete reboot.
Do you have a version of AROS that does that? I tried Icaros 2.1 in VBox and it reboots the machine instead of reseting AROS.
It is correct, I installed the ISO to HDD. I did a clean install with format and looking at the time of the files it is all the same so must be from same install.
Can you try booting from livecd and running SysExplorer from livecd to see if it crashes as well? I does not crash for me in VBox.
Almost on all ABI v.0 versions of AROS warm-reset is working including your 2016 version
When it did not work I'm most certain it was driver related, some hidd, but then it froze the machine and not turn off computer like like your 2017 version.
I tried the Live-CD of the new 2017 build and it is the same problem. SysExplorer crash and key combo. turn off hardware.
Edit:
I found out it is the native driver. On my hardware, IntelGMA.
Booting from VESA mode SystemExplorer does not crash. Key combo is still shutting down the computer.
