Nope, you're not the only one. Back a couple weeks ago this computer would crash every couple of days, total meltdown. It would start with a window not wanting to unhide itself or a program no longer responding, then it would move to another program, and another, and eventually the entire operating system would completely melt down and I would be forced to restart. I've also had issues where I completely lose use of my keyboard and track pad or when I click anywhere on the track pad, all I get is a right click and I'm forced to restart. Knock on wood, Lion seems to have started playing somewhat nicely and I haven't had any huge issues as of late. I'm sure they will continue to crop up until Apple finally patches this operating system up.
