not remembering full window monitor position

[baker_tony]

Hi, I've got a graphics card with monitor and TV out, running WinXP, dual screen - i.e. I have shared my desktop from my monitor to my TV (not cloned).
I was using an old version of BSPlayer (probably 3 months or so old) and everything was set up and working fine, when I double click on an avi, BSPlayer started up and went full screen on the TV and the controls where on the monitor.
Now that doesn't happen!
In preferences I have ticked "Always start in full screen mode" and "remember last movie position".
When I startup, it goes full screen on my monitor, I have to go back to window mode, drag the display over to the TV and go full screen again. If I quit BSPlayer and double click on the same avi, it goes full screen on the TV as expected. If I double click on a different avi it goes full screen on the monitor!
Any help appreciated.... is this a bug or is there some other preference I have missed...
Cheers,
Tony.
