I have created an application that uses Xforms to display design process
information. I have created some new object classes that act as an scrolling
canvas. However i've just migrated to Xforms v0.88
(previously using 0.81 & 0.86) and now the application does not work anymore,
debugger reports:
(debugger) where

(debugger)
The object ACchain contains a pointer to another object (C++ :-> ) via ob->spec
That object handles the drawing etc. it now seems that the ob->spec pointer
is corrupted, this did not happen in V0.86 & 0.81.
What happened?
