White Web Page from Sharepoint

[Bob]

Hi,

I have this huge problem...

I'm publishing Visio Organizational Charts as web page to a different portal
area in my SPS portal.
In these areas I have configured the home page with a Page Web Part linked
to the html visio page published.

When I try to navigate with my desktop (XP SP1) it does work without
problem. If I use other client (e.g. XP with SP2) whenever I click to some
link in the web part with Visio Page, I received a blank white page.

I tried to find some errors in event viewer, IIS or SPS logs files but
nothing....

If I try to access DIRECTLY to the visio published page, it works with all
the clients (SP2, SP1, etc...)

Any sugggestion ?

Thanks a lot in advance
