Please HEEELP: D2-D3 migration hell...

I have a 25000 lines user interface written in D2.
When migrating it over D3, compilation took me half an hour
(basically, changes in the uses...). But in run time,
while everything seems to work, it generated a
"EAccessViolation Error, accessing address 'FFFFFF...'. "
This problem does not exist in D2.
When tracing through the de{*word*81}, it is just AFTER the end of the event
of a speedbutton push. While the message tells me
to go step-by-step, there is just no line in my code associated to the
problem...
Please, help me getting out of that hell. Already spent 4 hours on the
problem....
Big big thanks !
Andre
