Is this a RC1.1 bug?

I've just installed the RC 1.1 SQL Server version onto my PC. And there's something happened which I'll try to express here.

1. Thank you very much for your hard work.

2. I just cannot create any subforum for a forum which has been a subforum already. In another word, I cannot create multiple stages forums. Yeah I don't think this is a bug, but if users can create multiple levels forums, it will be much better. I know you've stopped receiving ideas already, but, sorry,  I don't think you will make a sub forum system like this.

Or there's something wrong in my configurations?

3. I use Internet Explorer, and in my first post (first topic lol) in my testing forum, there's a message box like this (see the picture please)



Is there anything wrong? I've typed something in the Message text box, and I don't use any script blocking software.

Thanks for reading.

Regards.

I am having the same problem on one computer.  When I try on my other computer (different OS image) it works fine.  Both compuers are running McAfee 8.0.0.

I've actualy just noticed that this happens intermittedley for me if i use IE to write PM's also happens with all anti-virus / similer software turned off.
