I'm using the beta version of Photoshop version 13 and I've been getting apache errors a lot. I've done all my Adobe updates, but today, it went berserk. It gave me apache errors and it began opening hundreds and hundreds of new tabs in my browser and then started opening new windows all saying the same thing about an apache error. I had to shut down the pc to get it to go away, as the task manager wasn't fast enough to end all the new windows that kept popping up. After restarting the computer, and re-opening the program, the photos I was editing were found and brought back up, so nothing was lost. And it has worked since then. But I figured it best to report the issues.
