By default it is enabled but in theory they can switch it off in the Internet Options. However over 99% of web users do have it enabled, so I wouldn't worry too much about those which don't. Especially if it's an MM plugin, you can just tell them that they need to enable it! :)

Wait,

Is javascript always activated or does it depend on the user?

Internet Explorer always reports 4.0 to indicate that it is compatible with Netscape 4, it's been like this since about IE5.

I can only guess that when MM requests an OCX connection with IE8 it is running in IE7 compatability mode - at any rate this is under Microsoft's control and not something that can be changed by MM.

4.0 (compatible; MSIE 7.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0)

4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0)

I have IE8 Installed (Windows 7 x64) yet using JavaScript 'navigator.appVersion' I get in MediaMonkey
[code]4.0 (compatible; MSIE 7.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0)[/code]
For some reason all IE return 4.0, the important part is [b]MSIE 7.0[/b]

The same HTML opened outside MM, in IE8 returns
[code]4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0)[/code]
[b]MSIE 8.0[/b]

But I don't think the one in MM is IE7 given the way it handles CSS, it more like IE6 to me

What am I missing?

It's whichever version of IE that you have installed.

The which version of Internet Explorer is created by NewActiveX? 6.0?
