Freeze on start and when close bs player

[Vijetnamac]

I saw one thread about it, but no one offer any solution. I have powerfull PC, so cant be performance problem. On every start i see like one sec lag, then on closing player its same lag, little freeze. But, i am clicking every day on tens of videos, so its very anoying. I recently reinstalled Win, so basicaly BS player was first app installed for my pc, and its not problem interfering with other programs or setting. I tried everything (last version) including every video rendering, codecs, checking in general options...but on every close i see again lag, dissapeared mouse for two sec and whatever i tried doesnt work. Any solutions? I also set different priority, no changes.
