Error entering the forums

[ReadError 0]

For 2 days now, when I first enter the forums after opening my browser, I get an error saying in line 32, 'awin' is null or not an object. But the forums are working ok. I don't get the error again until I close my browser and reopen it.

I found the problem, I uninstalled Visual Interdev 6. It seems that it f*cked up something in the configuration.
