To test I just reinstalled BS.Player 2.62.1066beta.
None of the settings mentioned by you were changed.
"Automatically download online subtitles" still switched off
"Enable taskbar status area notifications" still switched off
"Seek by keyframes (AVI and MKV files)" still switched off
Rendering mode still unchanged (on a non-default setting for XP)
Location for downloaded subtitles still unchanged (fixed folder on F-drive)
In this connection note that the PC on which I tested, runs under XP SP3 (
so no EVR for me, that's why I selected Internal renderer DirectDraw surface for the test).
Also - as I have several versions/builds installed at the same time - I never install in default installation folder, whereas I also select settings to be saved in installation folder (i.e. also non-default).
