I'm having trouble accessing my email account while using OWB under MorphOS.
Once I've logged into Comcast, when I select email instead of giving me th email page it just refreshes the screen.

This does not occur on my PC under Firefox.

Any ideas?

You might want to try another Webkit-based web browser such as Chrome or Safari. Comparing Odyssey, which also uses Webkit, to a browser using an entirely different engine such as Gecko does not provide a lot of meaningful information.

My guess is it would work with Safari or Chrome, anyway. It's most likely related to cookies.
Is there a way to create some test account there?

I can try to create a sub account Fab.
Let me do that and I'll PM you the login info.

Ok, i checked and the "issue" is much more simple, actually: it's because the captcha uses Flash 9/10, which means it only produces a black square if plugins are enabled for this page. Once plugins are disabled, the site falls back to HTML captcha, and login works just fine.

So, either disable Flash for the current tab in menu -> settings -> plugins -> disable, or create yourself an exception for comcast.net in menu -> windows -> url settings and disable plugins for comcast.net (that way you won't have to disable Flash yourself each time).

Thanks Fab!
Not having to boot OSX, Ubuntu, or Windows to check my e-mail is very useful.
Now I can do this in OWB under MorphOS (and I no longer have to rely on anything else).
