What does the unimplemented trap bomb error message mean?


What does a unimplemented trap bomb error message mean? As in, what happened to cause it? Thanks! :)

P.S. Tried googling and came up with nothing :eek: :( ...reason I'm asking is because I've got a app I want to run on a 'ol SE of mine but when it starts to open a unimplemented trap bomb error message is thrown (Mac OS 7.1) and thus I'd like to know what exactly happens to cause that bomb...thanks! :)


It's most often a program bug. Or the app doesn't play
nice with 7.1. Nothing for it unless you're the programmer.

An unimplemented trap basically means that the software tried to call a routine that wasn't there. If this is happening during startup the most likely cause (though not the only possible cause) is a non-Apple extension/control panel that isn't working quite right, or that expects a newer (or older) version of the OS than you are running. If the problem is reproducible (i.e. it happens every time you startup) you're in luck; you can restart without extensions by holding down the shift key, then try removing any third-party extensions and control panels and adding them back in slowly, rebooting each time. When it starts crashing again, the last one you added in is probably the culprit.
