__doPostBack is undefined on DotNetNuke website for IE 10

I have a DotNetNuke site, and today a customer called in and said it wasn't working on IE 10. Specifically the login and register links weren't working, but they do in compatibility mode. I took a look on our test windows 8 machine and saw that it was failing because __doPostBack was undefined. I've been searching for a fix for the last 6ish hours, and what I've been able to find is that apparently the IE10 user agent is covered in the ie.browser file and that I should install this hotfix and reboot the server. That didn't work. I haven't noticed any changes, even though I think the new ie.browser file should match the new user agent.

What other steps can I take to fix the problem? Note: the server is running .NET 3.5 with service pack 1 on Windows server 2003. The site is running DotNetNuke 05.06.02. Any suggestions would be greatly appreciated.

On my production site I tried a few things and they didn't work.

I installed the hotfix and rebooted - no good

I copied over the updated ie.browser file - no good

I tried modifying the default.browser, the ie.browser, and the mozilla.browser files to enable javascript for everything - no good.

One thing I did that finally made it work (and this should work for EVERYTHING) is in the InitializePage function of the Default.aspx.vb file, I added this line to the start of the subroutine

Page.ClientTarget = "uplevel"

That should (from what I understand) treat ALL browsers as if they can handle javascript and cookies and all that other stuff we need. I feel like that's a pretty safe bet.
