Full screen bug with 2 monitors

[Gare87]

Hello, i encounter this very annoying bug, i use 2 monitors, both LG one FHD and one 20" 1680rez, i tried to change render options but non of them works, i installed BS suggested codecs even if i had K-Lite codecs...problem is when i put Full Screen(or regular window, it does not matter) on 20" monitor and Full Screen game on second 23" monitor, BS player crashes, freezes, or in some cases video blinks and continue to work but then subtitle is gone(not using direct vob sub), so i need fix for this or configuration settings(options to turn on or off) to get this working if possible...i am using BS player 2.70, build 1080 i think, but that does not matter it happens on older or newer versions...tnx

P.S. Other players are working fine!
