Rewind & Fast-forward with arrow keys, etc. not working.

One of the main reasons I like BS.Player best is because of the option of rewind and fast-forward with the arrow keys.

Recently, I don't know what's wrong, but it stops working, also if I want to switch from small screen to Full Screen view I usually just double click on the screen and it changes, but that's one of the things that stops working too. I uninstall and reinstall BS.Player and it works again. Is there some other way?

I currently use BS Player Free Version: 2.58 Build 1058, 08 Sep. 2011

Default keydefinitions for arrowkeys are "Seek forward" and "Seek backward".
Default keycombs for "Rewind" resp. "Fast forward" are [Ctrl]/[F6] resp.[Ctrl]/[F5].
Default key for full screen switch indeed is double left mouseclick (and/or depressing [F]-key)
(This post also refers to these functions)
It seems someone(/something?) may have (accidentally?) changed keydefinitions of your BS.Player.
You can verify settings under
(rightclick >) Options > Preferences > Keydefinitions & WinLIRC
:wink:
Pse note settings for 'Windowed mode' and ''Full screen mode' may be different, so to be sure for both modes, you have to verify both.

Probably your settings.xml file got corrupted. Just click Reset to default values in Key definitions. But this will only temporaily solve the simptom, not the cause.

Little off topic - default keyboard shortcuts are listed here:
