Unfortunately not. It's a compiler/framework shortcoming that the  
vendor hasn't resolved yet. At least it doesn't crash the entire app  
as with V1...

My strategy is to dot the code with

    debug "Point A"
    ...
    debug "Point B"

etc. and narrow down the line of code that's causing the problem (i.e.  
if the Debug window has "Point A" but not "Point B" then you know the  
exception lies somewhere between).
