Problem with acedSSGet()

Hi,

My product uses acedSSGet() to create entity set from drawing. i am working on VS 2005 IDE.
The problem is that acedSSGet() works fine when i build the project in debug mode but in release build mode, acedSSGet() does not populate all the entities in the output selection set. i am working with Selection Code "C" as i want to select only Crossing entities. Again, while running debug build the function includes all the crossing entities, but in release build run, it does not include certain crossing entities in selection set. Is their any certain reason for this behavior. How to correct it, please help.
