Frame capture freezes BSplayer

When I try frame capturing something on BS, usually the first capture works and then when I try the second, it just freezes and I have to close it from the task manager. Sometimes it freezes on the first try.

I've tried the different overlay modes, and the different settings of Convert captured images in software, tried using .bmp instead of .jpg but it still doesn't work.

I don't know what else to do.
