Guess you can't get round the way IE works. Very odd though that the PreviewKeyDown fires twice. Picking up F11 twice would be OK bbuutt ootthheerrwwiissee......

>What I am trying to achieve is acctually really simple. I just want the form go to full size just like IE does when F11 is pressed. I got it working now with some small exceptions, but those exeptions are also present in IE so I think I am good to go.

>>OK - I see what you mean. But, for me, the PreviewKeyDown fires except when the document area itself 'has focus'. It the PDF Reader toolbar has focus then I get the event. I suppose this is dealing with an ActiveX actually hosting a second ActiveX (the PDF Reader) :-{

>>And just to confuse matters more I see that the PreviewKeyDown fires *twice* for each keypress on the WebBrowser control.
