OK, commited.
I also changed the verification about reboot to be asked unless user has
specified alert level to be fatal (earlier this dialog was shown only on
"warning" level i.e. not by default).
Btw. Why toggling WinAUE CPU cycle accuracy would need reset:
#if ENABLE_WINUAE_CPU
/* Did change CPU cycle exact? */
if (changed->System.bCycleExactCpu != current-
>System.bCycleExactCpu)
return true;
?
(changing UAE CPU cycle accuracy System.bCompatibleCpu setting
doesn't trigger reset.)
