“I’m surprised that you can’t upgrade on your computer..”
I tried FF 4.0; but had to back it out. I was receiving ‘screen over writes’ on the tool bars and various sections of the display screen, making the current screen unreadable. Almost as if the screen was not cleared from the previous display. FF was no help they told me to upgrade.
Did you try changing the ‘font’ size under ‘Content’?
It should have fixed that problem although most of the time ‘fold overs’ of the screen are related to a Graphics driver problem, and not a program fault.
