When I am typing using Internet Explorer 7 (Version 7.0.5730.11), some keystrokes are not registered and don't show up - this happens when I'm typing in a form, an input box or entering a URL address. Typically it's about 1 of every 15 keystokes, but it's definitely variable. If I am very deliberate and slow down my typing, it's not a problem. A likely related issue is that my text cursor blinks in an erradic manner in IE 7. This is not a problem in non-IE applications (Word, Excel, etc.) I have run Spybot and Adware checking for malware, and found nothing. If it matters, I'm running XP Media Center. Any thoughts? Thanks in advance.
