Chrome causes problems on my company's asp.net site also. I checked browser info for people logging in using diffrent browsers.
As you can see the Chrome is missing the .NET CLR, at this point I believe this is causing the problem, If I find a work around I will post it, but I will be doing it in my time as it is a company only site and they do not care about cross browser compatibilaty.
