This problem is getting really annoying, as I usually list 5-15 items per day. I think I'm going to email about it, is there anyone else who'd like to be included as a signature on the email?
I was figuring I'd send something to the effect of-
"Dear Apple,
Like most Apple users, we downloaded Safari soon after its release and have been using it nearly exclusively ever since. As the new versions have been released, bugs have been fixed to the point that Safari is becoming a stable and high-qualty browser. However, there is one problem that has continued throughout Safari's development: the browser's complete inability to work when selling items on EBay. There are many problems Safari has with EBay, but most noticeable are the fact that Safari crashes whenever trying to upload pictures to the EBay site and that it is incredibly difficult, if not impossible, to revise auctions when using Safari. As EBay is one of the most popular sites of the web, it would seem necessary for the future success of Safari that all of these problems be worked out. For the signers of this letter, in fact, Safari's problem with EBay is the sole reason that many of us are still using Internet Explorer. We request that you address the problem in the next version of Safari. Please keep us posted.
Regards,
..."
