Whereas the behaviour as mentioned in the previous post is e.g. also valid for BSPlayer 1.37.826, when going even further back in time it was different in e.g. BSPlayer 0.86.501.
If version 0.86-BSPlayer is closed in full screen-mode, next time it also starts up in full screen mode.
This indeed seems a more logical and consistent behaviour to me (but that's only
my personal opinion).
