Keystrokes skipping

When I am filling in an interne form such as this one, certainkeystrokes including the spacebar just skip. I do not have his roblem whn using pograms such as Excel or Word or other pc based programs, only internet. I have intentionally left typos to show the problem I am having. I constantly have to go back and reype the keystokes and it is very irritatig. I am a great speller ad decent typist These errors are al keystroke omissios, not entry rror. Hasanyone herd of ths poblm?

I had a similar problem where it sent me to the start every few characters (like pressing the home key) which made things impossible to reply to on forums. Everywhere else was fine though, so i just wrote my reply in notepad then pasted it in. It's a rough solution but it's not that much trouble really. The problem fixed itself when i formatted my hard drive because of an unrelated problem, and i never bothered to find out a proper solution. Sometimes the simplest solutions are the best
