Inconsistent viewing issues in Powerpoint 2003

Hi there,

One of my colleagues has embedded some Xcelcius slides into a Powerpoint presentation. When he views this using his copy of Powerpoint 2003 it loads and runs ok.

When I try it, all I see is a white screen. The flash object appears to load (i.e. I get the flash player right-click context menus) but it wont play the slide. The same applies to some other machines running Powerpoint XP and 2003.

The weird thing is, we've tried it on a number of machines, including a RemoteApp server and it works for those.

We are all using the EXACT same version of Flash and Powerpoint (where our client we would like to present to is using Office XP). I cant explain why this is working for some and not others.

I have checked and turned off Macro security and even updated Flash player on every single test machine we tried this on with the same results.

Anyone have any idea whats causing this inconsistent problem?
