Hi, I am having a problem with System Preferences freezing up when selecting Accounts. Everything else on the system works fine. I activated the Guest account for some file sharing then according to me deacitvated it but now it appears on my login screen however when I click the account icon on system pref it freezes The only way to unfreeze is to select something else on the Dock (which doesn't magnify as it normally does), then close that and go to back to System Preference and then close it. Or select something else from the dock and then Force Quit the Systems Preferences. The whole system preferences closes and I will get an error message and the problem details (which I know VERY little about) show an Exception Type: EXC_BAD_ACCESS (SIGSEGV) and Exception Code: KERN_INVALID_ADDRESS If that helps. "Heres the copy paste Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x0000000116dcf820 Crashed Thread: 0 Dispatch queue: com.apple.main-thread" I tried restarting or clickin on it but the same error message appears. Any ideas on how to get back the the default or fix this problem are greatly appreciated. Thank you!
