I hope this is the right place for this. I went to the Apple support forums, but so far I've got no replies, and I really do need to use my computer today so I thought I'd come here and ask the same question I did there. This is a problem I've been seeing ever since the first day I turned on my new iMac, but it's never given me enough trouble to bother asking about it until today. Before today, it would just drop the "I's" or "G's" in a paragraph, and a simple restart of the application would fix it. However, as you can see in the image above, it's gotten pretty bad, and I'd like to know what's actually going on, and maybe find out how to stop it from happening. This is unbelievably annoying. So far, it's happened in Firefox, Safari, Camino and iChat. It occurs on most websites (however this forum displays correctly, thank goodness). I'm at my wits end here, and I don't know what to do. Help!
