Flash EXE on Japanese WinOS

hi all,



i'm testing a cd presentation, (flash standalone exe)

and it works fine on Windows OS English and even on mac.



However, on Windows XP Japanese OS, it gives inconsistent
results.



some people can see it, while some see just a white patch
full screen.

these same people however can see the presentation through
the browser

(i have included an html file with swf version of the exe,
just in case)

and they were also able to see the full screen standalone

when the required files were accesed from a USB pen drive.



is there a documented issue of any problem with Japanese
Windows OS?

or is it just some coincidence and actually an issue with
individual security settings?



thanks in advance,

kedar
