Problem with dark colors...appears a strange green line

Well I've installed FlyakiteOSX on WindowsXP Sp2 and works good.

There's only a little problem: when I open a dark grey or dark blue image, appears a green line in the middle of the screen (pixel problem? I don't know).

Now It should't be a monitor problem because it worked good before the installation of the software.

I've got a Toshiba Satellite P30-109

(Notebook Processore Pentium 4 a 3.06 GHz,HD 60 Gb, 512 Mb RAM DDR, DVD±R/RW e DVD-RAM, Display 17'' TFT...etc.)

Can you help me to solve this problem?

Sorry for my English

Thanks
