The helpfile says:
Occurs when there is a run-time error in a method.

The Error event allows an object to handle errors. This event overrides the current ON ERROR routine and allows each object to trap and handle errors internally.

Note The Error event is called only when the error occurs in code.

So, if the error() method is filled with code, it overrides your ON ERROR setting. And it only is called if the error occurs in a method. Perhaps the type of error varies for form1 and form2?
