Flash

It won't affect MP3 audio, I don't think, but any videos using Flash (like Youtube videos) probably won't play on your computer if you don't have Flash installed and working on your local computer.

Thanks.I hope you are right.There was a period when I could not get sound interviews to work from Scientolipedia. I had to extract the file name (via history) and play them separately. This got handled when I updated Flash.
