Multiple screen problems

[Aiken]

I am currently using BSplayer Prolite V2.24 on windows XP SP2.
AMD X2 4600, 2GB RAM, Nvidia 8800GTS.

The Issue I have had this happened over several previous version of BSplayer as well.

If I try and drag the video pane between either of my screens (regardless of if the video is playing) BS player crashes with the following error:

BSplayer v2.24.954, Unhandled exception at EIP: 01CC0520
If you click 'Close' application will be terminated.

I can't now change the screen its playing on unless i reboot. It makes no difference what Codec the video is in. It does not happen with DVDs though.

Also as I have one screen sat above the other and I use the top screen for watching stuff on. When I move the cursor to the bottom screen the control bar you get at the bottom in full screen mode then popes up as i would expect, but If i move the mouse back up to the top screen the control bar is then displays at the top of the screen below as in the attached pic.

Please can you advise.
