I am using Windows 7, and IE8.
Every time I have GMail open in IE8, and I resume from sleep, I get the question about working offline - even if at that momoent the wireless connection is available.
This is particularly sad, because all browsing is stopped until I dismiss that dialog, that may be hidden below other windows.

As I am not using offline browsing at all, is it possible to disable the functionality altogether, so that I no longer get the question? A bit like in Firefox, where I simply get the error message with page unavailable.
I have googled a bit, but no luck so far. Even a direct modification of the registry would be fine, for me.
