anti-forgery and time-out when posting content

I get the exception below in my IIS Express trace logs when I am editing content and save or publish it on my local box using Win7, SQL Server 2008 R2, WebMatrix or VS2010.  It is a frequent but not consistent error.  I get the dreaded 500 error after a pregnant pause while "connecting" to the server.  If anyones has a clue or event thinks they have a clue about what it going on here.  I would appreciate your feedback.

Do you have a machine key configured?

Sorry I forgot to mention I have been through that information. Here is the entry I have in my web.config in the system.web. I did this quite a while ago with no change in the behavior.

<machineKey decryptionKey="6F30126FFDE71DC60289780A772735BBEF74A9A534AD2BE75A3DB098488DF549,IsolateApps" validationKey="AA3F6A45BAD3DFD7407580520C450584CF1073D8D4AE058D3CD7B7E7AEA7075BDDAFE16D9A42DE7552704D31B33A4E9B3D6470D85E62CB89AA3204C6C617BAA9,IsolateApps" validation="SHA1" decryption="AES"/>

Thanks for the response,

Well now you machine key is public, you can change it ;)

Is anybody else seeing that? You should file a bug in any case (and change your machine key, Sébastien is right: your machine key is a secret).

Don’t worry, it was replaced Immediately after I sent it to you. J

I wanted to follow up on this. I tried editing content on my hosted site instead on my box and not an issue. So it was clear it was my computer and not anything about my Orchard installation. So I do whenever I have weird and unusual behavior in my software that seems to have no basis. If you guessed rebuild my box you just lost ten points. J I turned off my anti-virus software, AVG. Haven’t seen the problem since I did. However, I have not added a lot of content. So I don’t know that it is the cause conclusively but there is strong evidence.

I thought you might want to know.
