Alex:
I wrote the PPI 'Application'. Running another app from within aa
application is tricky. The application must run with no access to global
variables and have no static vaiables of it's own. If you look at the PPI
code, you can see how this is done. _All_ variables must be passed to each
function that uses them. If the application is set up to 'return to the
previous app' (Plucker has a configure switch for this), It can re-start
the application it came from. Check for 'RETURN_TO_PREV_APP' in the viewer
code.
