Ok.... Here's something interesting...
I have Paralells Desktop on my iMac. It's a system that allows me to run Window or other operating systems in a window, while running OSX at the same time. It's similar to VMWare, if you're familiar with that. I tried using both IE and Firefox on Windows through Paralells Desktop, and everything lookd fine. The two accented letters (eta if I remember my Greek alphabet correctly) and the final sigmas showed without a problem. So, it seems that you have indeed fixed the problem. Now, if I could only figure out what the problem is on my end.
