What's the catch with ROSA on Windows client PCs

[Joaquim Pinto da Costa]

I understand that this has may have been asked times and times before.
But what's exactly the client requirements to run ROSA enabled sites?

On some Windoses it runs fine on others just a blank screen.
I thought it was Microsoft Java VM, no avail.
I tried several versions of JAVA still no luck.

I admit that my approach was not very scientific and I should have
been more careful in trying to isolate the problem. Now I'm on a
deadline and out of ideas.

Any help would be VERY welcome

Joaquim (frustrated)
