At "appears" that many people are having problems with SL, IMO, it's many of the same people posting different issues. So just to clear up confusion and help everyone using Snow Leopard please post your install method and how you reinstalled your apps. For me, for each of my Macs I used Disk Utility, erased the hard disk, began the installation of SL, when I got to the desktop I manually installed all of my apps. Everything works perfectly including my apps. No problems at all. Please join in.
