The game Richard Burns Rally does no longer get any events. The game
worked after some patches some month ago from me. As i had no intention
on that pages to make things right but to make the game work i might
have not picked the optimal solution. But this patches fixed all the
apps, that worked with their own DataFormat.

So the problem is like that:

The old code copied the default constant format and applied
caclulate_ids on it. So the dwTypes where set with proper
MAKEINSTANCE(...) calls. So an app, that requested later its own data
format with SetDataFormat using the data from EnumObjects. After the
change now the default const has ANY_INSTANCE all over the place but the
app request a certain instance - so on SetDataFormat there are no
matches.

So the big question is: is our SetDataFormat wrong or is this patch
wrong? Please advice.
