Safari frozen on start-up, won't open

Question

This morning, Safari spontaneously started freezing when I try to open it. Nothing new, haven't updated it recently. Everything was working fine then all of a sudden it's not working anymore. I click the Safari icon in the dock, I see the Safari menu bar at the top of the screen, but the browser window never appears and I just get the pinwheel. Totally frozen.
I repaired permissions, but that's didn't help.
I deleted Home/Library/Preferences/com.apple.Safari.plist, but that's didn't help.
I tried to locate the most recent crash logs for Safari in Home/Library/Logs/CrashReporter/Safari.crash.log, but there were no crash logs for the recent freezes (most recent crash log dates from mid-july).
HELP?

Tengen, do NOT try to delete Safari, you will only make matters worse.
All downloads of Safari 3.1.2 are updaters. The reason why Safari will not install on Leopard is that this Safari update was included in the Leopard 10.5.5 updater.
The only way you, on Leopard, can reinstall safari is to use your install disk to install the version that is on there, then update it in the usual way.
Deleting applications and reinstalling them is NOT the Mac way, that is a Windows thing!
If your Safari won't open, one or more of the following procedures should fix it:
1. Go to Home/Library/Safari/ folder and remove the following two files:
• history.plist
• lastsession.plist
(Safari may not load properly If these two files are corrupted.)
2. Go to Home/Library/Caches/Metadata/Safari/ and remove the contents of that folder.
(These are just webhistory files and are not required for Safari to run. However, similar to preference files, problems can arise if they have become corrupt.)
3. Locate the cookies.plist file that's located in the Home/Library/Cookies/ folder and remove it.
(Again, faults in stored cookies may interfere with Safari's launch.)
4. Check whether any of your third-party internet plug-ins may be interfering with the launch of Safari by carefully moving them to the desktop (do NOT delete them at this stage). You can find these in two places:
Home/Library/Internet Plug-Ins/ folder, and Global plug-ins are located in the Macintosh HD/Library/Internet Plug-ins/ folder.
Restart Safari and place them back in the correct folders, one at a time, closing and re-opening Safari each time. If you discover that one of them was causing the problem with launching Safari, trash it and download and install a fresh copy.
