I cannot reproduce your problem. When I custom-position subtitles, that position is remembered. So maybe the problem is that BS.Player cannot access its settings file. Maybe it is an UAC-related problem (users-rights/privileges especially under Vista & Win7). Are other settings, when changed by you, remembered?
Unfortunately you didn't give any info at all on your system, nor about the BS.Player version & build number you're using.
The forum is basically run by fellow-users. (I'm also just a user, no programmer nor developper.) If, based on the information you've given, users have some idea how to help you or point you to the right direction, they will do so.
P.S.:
Purchasers of BS.Player Pro need not depend on this forum, as they are entitled to get direct e-mail support from BS.Player-team members through the [
