Hi Carl,

I think your problem could very well be caused by the bug in IE where IE 
requires a blank after the colon in some HTTP headers, although this 
blank is speficied as optional by RFC2822. This bug is taken into 
consideration by VW 7.5 but not by 7.4.1.

If this is your problem, then you will be able to fix it by patching 
VisualWave.Response>>writeCookies: and 
VisualWave.MessageHeaders>>sendOver: making sure a blank is inserted 
after the colon in 'Set-Cookie: ' and in ': '. You may also want to get 
a more recent version of Seaside 2.6 from the public Store. Seaside 2.6 
includes these fixes since 2.6b1.118.1.
