A few days ago my computer (dual 1.25 MDD, panther 10.3.3) began acting very strangely. Applications are crashing all over the place, among other things. Basically it seems that whenever an application tries to show a warning dialog box (like when resetting an application, or when safari can't find the server you're looking for) the application will unexpectedly quit. It happens *almost* every time a dialog box pops up, in every application. Even "do you want to save?" dialog boxes cause unexpected quits. I should clarify...save boxes only cause crashes if i am saving preferences, not documents or files. I have a second account that I use to troubleshoot, and the problem does not appear in that account. I'm thinking that some of my user preferences got screwed up, but I don't know which plist to trash...i'm still a bit of an newb on OS X... Also, I have Cocktail and have nothing it can do has helped, i.e. clearing caches, repair permissions, etc. It also might help to know that the crash log this problem gives me always has this line: Exception: EXC_BAD_ACCESS (0x0001) Codes: KERN_PROTECTION_FAILURE (0x0002) at 0x00000006 That "kern protection failure" part sounds bad...kernel panic???
