Other problems with Safari aside, this sounds serious:
"I option clicked on a link in Safari to test a download. The download changed to the name of my home directory as it was downloading. It saved into my User folder. In the blink of an eye, it removed, destroyed, evaporated, my entire Home directory, including the desktop which disappeared along with days of work projects that were on it! Safari itself disappeared because it was on the desktop. My multi-gig directory was suddenly only 32k"
