Protected Applications and Alt-key processing

I've been struggling with this for quite a while and just saw the issue of Firefox crashing on launch correlated with Protected Applications.  Yeah I've had that happening for a couple weeks and blaming Win8.  But something I've been struggling with even longer is Opera (another protected application) and using the simple and common Alt-D keystroke that simply positions the focus to the address field.  Then I had the same problem in Quicken 2012, but only on one screen where I happen to use the Alt key as a short cut.  So Webroot Protection (identity) seems to be a common link.  Disabling all of these applications from "Protected" seems to resolve the problems.
 
What's going on specifically is this.  In Opera, when I press Alt-D, focus initially shifts to the address field (as you'd expect it to) but then when I release the Alt key (in slow motion, one hits Alt, then D, then releases D, then releases Alt), focus shifts to the File menu item (as in File, Edit, etc)...it doesn't cause the menu to drop down, but highlights File and then I need to hit escape to clear it.  So it's as if the Alt-key "KeyUp" event is being sent again.  I'm in their beta program and can't tell you how many times I reported this and now feel more than a little foolish.  Also, pressing Alt and any of the File menu shortcuts sometimes works and sometimes does nothing...disabling Weboot Protection causes Opera to work as it should.
 
I'm running Win8x64, Opera 32-bit (current version) where the problem is easy to recreate.  I guess consider this a bug report...?
 
Thanks!
 
PS - I'm on the weboot essentials still as I was notified I'd be updated automatically to complete, but that has yet to happen.
