screen doesn't turning off after using bsplayer

[noron]

hi
i have bsplayer 2.32 build 975 free version
and every time i run bsplayer something change in my power options
in "turn off monitor"
i don't set a screensaver
only after 2 minutes i don't use my computer the screen is turning off
but when i run bsplayer and close it
my screen doesn't turning off anymore
and the weird thing is that nothing change in power options
the "turn off monitor" still set to 2 min but doesn't turning off
not until i press the ok button in power options

it happens only after i run bsplayer

is there any way around it? a fix? solution?

thanks for your help in advanced !
