Type 1 and 2 errors may also be triggered by extension conflicts

Quote:

Type 1 error (Bus Error) One of the most common indications of a memory-related error. It means that you tried to access an non-existent/inaccessible memory address. Common causes and solutions: Init/Extension or Control Panel conflict. insufficient memory for the operation being attempted, you could try allotting more memory to the application. Type 2 error (Address Error) Very similar to a Type 1 error. Some piece of information was written to the wrong place in memory. Attempting to access data larger than a byte on an odd address (68000 processor) or an instruction at an odd address. Common causes and solutions: Init/Extension or Control Panel conflict. insufficient memory for the operation being attempted, you could try allotting more memory to the application. The instruction being requested may not be supported on the CPU. i.e. an 030 request on an 68000 processor
