subtitles bug in bsplayer build 500

[onthewayhome]

bsplayer is forgetting subtitles on screen if you choose full screen and put them in auto mode or out of movie (on black part of screen, out of any video black screen). works fine if subtiles are over the movie at any window size. OS tested: win2k sp 3 and 4 and winxp sp1. subtile sample (from hellraiser, brazilian portuguese):
1
00:02:01,008 --> 00:02:03,469
O que ?© do seu agrado, Sr. Cotton?

2
00:02:05,095 --> 00:02:06,263
A caixa.

3
00:02:17,858 --> 00:02:20,110
Leve-a, ela ?© sua.

4
00:02:25,741 --> 00:02:27,451
Sempre foi.

5
00:05:55,450 --> 00:05:56,827
Tem que ser uma dessas.
