	Thanks! Your extensions include BlockContext>>on:handle:. Which interface uses that message? I've not encountered it before (in VisualWorks or ANSI).

	As Vassili pointed out, you need to use a different handling request message to handle a proceedable exception (>>handleProceedably: instead of >>handle:). This was intentional. I wanted each situation to specify whether an exception may proceed, and leave the actual proceedability of a particular exception as a context-specific choice. An exception for a proceedable situation does not have to be proceedable. I've encountered many situations where the proceedability of an exception depends on highly dynamic information.

	In the interest of conservatism/paranoia, I decided to assume non-proceedability for a particular exception unless explicitly specified with >>handleProceedably:.

	I hope that makes sense!


	thanks again,
