Text not showing

When ever I type something in FF or Opera it sometimes randomly disappears. And when I load pages the page is badly formatted and some text doesn't show.

Ehh.

 

I've had this error before. I forget what I did to fix it >.<

Does it do the same thing in IE 7?

 

No. >_>

 

reinstall them if you haven't already

 

Methinks you has spyware/malware that types in backspace or delete in your proggies

SCANZ plocks.
