Does anyone have any information on why the web lead capture form would work on IE and not on FF?

Ususally it's the other way around, something works on FF but not on IE. Is there some patch that I should be downloading?

When redirecting in IE, the lead is captured correctly & the lead is redirectled correctly.

In FF, the lead is captured but the lead is shown a blank page.

I'm using CE, version Version 5.2.0c (Build 5505)

Any help on this would be appreciated as this is holding up my implementation of this system.

Regards,

Pattie
