Programatically deactivating a feature in Internet Explorer

I'm currently developing a plug in for开发者_高级运维 Internet Explorer, and there's a certain feature in Internet Explorer that's bothering me.

There's this feature in IE that's been appearing at least since IE7 (I couldn't check earlier versions), that lets the user modify the sizing of HTML elements in editable windows (such as a rich text mail in GMail), just by clicking on the element and dragging the sizing box. This modifies the style of the HTML element (such as a <img> or a <div>).

My first problem is that I don't know the name of that feature. I've searched and searched, but I haven't been able to find a thing.

My second problem is that I need a way to either turn it off, or at least to work with it, programatically. In my plug in, I need to modify the DOM in webmail clients to modify certain things that the user types. The problem is that for some reason, the behaviour of my plugin varies if an HTML element is selected using this feature in the edit window of the webmail. I need to, at the very least, be able to detect if anything is selected this way.

Any help will be appreciated. Thanks a lot!

You're probably talking about Internet Explorer's Accessibility Features, which are designed to assist the visually impaired to use websites. Visual impairement can take many forms, and it's generally considered very bad form to take away any tools designed to assist users in their efforts to effectively use the Internet.

Don't make your users work harder to use your site. You get paid to write software that's easy to use and makes life simpler. If your site doesn't do that, your users will find one that does.
