To drag an icon out of the toolbar, at http://phphtmledit.com/EnableAll.php press on an editor toolbar icon and drag it onto the page.

 No special techniques are required it just happens. When I am working quickly it can happen unintentionally and an icon image then displays within the text at the location where the  dragged icon was released.

 

I am using Vista, which may be part of the problem.

 

Thanks

David
