executeCommand failed! when NavigateTo

[Aga]

I'm testing some urls in my tests and sometimes I've got 
ExecuteCommand failed!
BrowserCommand (Type:'Information',Info:'DocumentMarkup',Action:'NotSet',Target:'null',Data:'',ClientId:'09d3436d-e7e3-42aa-bd1a-1214bf54e2a8',HasFrames:'False',FramesInfo:'',TargetFrameIndex:'-1',InError:'False',Response:'')
InnerException: System.TimeoutException: Timed out waiting for command to be handled

   at ArtOfTest.WebAii.Core.Browser.ExecuteCommandInternal(BrowserCommand request)

on 
browser.NavigateTo(url);

Testing page have flash elements and sometimes snippets. I turn off autoWaitUntilready setting.

I've checked browsers and system configuration. I'm using 2010.3.1421 webaii version and I'm testing on windows server 2003.
I run it in all browsers (IE7, IE8, safari and Chrome) and in all of them it's the same issue.

Hi Aga,
    would it be possible for you to allows us to access your application? We would like to reproduce this issue locally. You can share the necessary info in a support ticket. Unlike a forum thread support tickets are completely confidential.

Are you aware that Test Studio doesn't support Flash testing? It's not the presence of Flash in your application that's causing the issue but you should be aware that recording on Flash elements within a page will not function.

Hope to hear from you soon!

Can I send test files by email? I wouldn't like to paste them on forum.
