Hello,
First I would like to say that I have been using your menu control for almost 3 years now and love it.
I have a question with respect to the menu control and my site, however I don't know if it has to do with the menu control or some other aspect of my site.
When search engines crawl my site I frequently get error messages akin to the following:
Message Length cannot be less than zero. Parameter name: length
Server.GetLastError.Source mscorlib
Server.GetLastError.StackTrace at System.String.InternalSubStringWithChecks(Int32 startIndex, Int32 length, Boolean fAlwaysCopy) at EO.Web.Internal.ee.a(String A_0) at EO.Web.Internal.ee..ctor(HttpRequest A_0) at EO.Web.Internal.bu.a() at EO.Web.Internal.bu.a(EventHandler A_0, Boolean A_1) at EO.Web.WebControlBase.OnPreRender(EventArgs e) at EO.Web.WebControl.a(EventArgs A_0) at EO.Web.BaseNavigator.a(EventArgs A_0) at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Control.PreRenderRecursiveInternal() at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)
Have you ever seen this error and/or what causes it? If you could help point me in the right direction that would be great, if not, I'll just manage :)

Hi,
Glad that you like our product. The error message you saw can be safely ignored. The problem is caused by some search engine uses an agent string that is similar to FireFox but did not include a correct version number. Our code sees it as FireFox and then try to parse the version number. This fails and throws an exception.
We have coded to ignore this error in more recent versions. So if you switch to a more recent version, you should no longer see this error message.
Thanks!

Thank you for the reply. Do you know what release this was fixed in?
