I suppose you see, sometimes, that stepping "into" a RAISE statement 
does not have effect.
I think you see that because there is no gambas code devoted to handle 
that particular event, so the debugger executes gambas internal code, 
which does not find any handler, and so goes on to the next statement.

For example, you have a class "Class1" which at a certain point does

    RAISE TestEvent

If the instantiator of 'Class1 as "testClass"' does not have a 
testClass_testEvent() method, then stepping through "RAISE testEvent" 
will lead to nothing - similar to a void statement.
