I'm not sure if this going to work, however I have encountered the
aforementioned crashes as well.

The problem is that you are trying to delete an object that has not been
created.  In order to overcome this, in your Init constructor initialize all
HBitmaps to nil (ie: QueenOfHearts := nil;.)  Then in your Done destructor test
to see if the variable is nil, and if not then you know that you have
created (allocated space for) that object (ie: if QueenOfHearts <> nil then
DeleteObject (QueenOfHearts).)  Sorry if my syntax is incorrect.

Hope this helps.
