associated bsplayer files bug..
 

when playing a movie file in bsplayer (really playing) and movie files are associated with bsplayer, double clicking on a movie file in explorer will not result in playing the file. When bsplayer is not running double clicking will result in playback...

I disagree, it works perfectly for me under WinXP, WinMe, Win2K and Win98Se.
I mean that if BSplayer is playing a movie and I run another movie with double (or single) click from explorer, the previous one is closed and the new one is open with BSPlayer.

You should give more details for investigation.
- Running the debug version would certainly help, because events are recorded in the c:\bsplayer.log file. But don't forget to run the standard version once in order to restore in the registry the good path for the movie files associated application.
