release problem

[gamecocks]

If I run debug version, it is fine. But I run release version, it crash. In particular, In two combo box, one determine what other show. It say the memory could not be "written". I have no clue about this. That is GUI part. Engine part is similar. Debug version is OK. release version is not. Illegal instuction It is not assertion and verify problem. Thank you for your help.
