macbook osx10.5.8...a window stating "the application crash_report_sender quit unexpectedly" continues to reappear despite selecting any and all options (ignore, report, or relaunch)...if anyone has any advice it would be appreciated.

Hello, you have to use the tiny Camera icon in a Reply to uplaload the pic, drag & drop looks lke it works until you submit the post. 🙂

Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions.

(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)

You can disable the Crash Reporter dialog box by launching the Terminal and entering the following command:

defaults write com.apple.CrashReporter DialogType none

and you can show the Crash Reporter again by entering the following at the command line:

defaults write com.apple.CrashReporter DialogType crashreport

Reboot.

Try re-applying Apple's Combo update for Leopard here:

Apple no longer accepts crash reports from Leopard. This does not explain why the program itself crashes, but why not simply disable it as BDAqua wrote.

I think all Crash Reports go to the round file myself. 😟
