>I knew about the fact that if the font size was specified, the ctrl+wheel made no difference in IE6. From what I can tell though, ever since upgrading to IE7, ctrl+wheel broke the font sizing for all fonts when displaying HTML in the browser control! It simply does nothing. I wish someone else can confirm what I'm seeing.

Yes, I confirm it. I tried with microsoft site and if launched from VFP, Ctrl+wheel does nothing, but from IE itself it works.
